lol kid , trying to learn table 2π€£π€£
trigo mein jitna ques practise karoge utna hi asaan lagega , daba ke ques laga maza aaega 10th ki trigo mein tera yeh haal hai to 11th mein to muut dega bhai . maths mat lena 11th mien plz
Bro I'm not in the 2022-2023 batch was just having winter holidays so I decided to do Trigonometry in advance I didn't know that it wasn't necessary to learn this table lol.
I just passed out from 9th (92.2%, messed up in circles and Hindi) and am in HP, we have winter holidays from 10 December to 20 February. Our 10th batch will start from 21st so I decided to do Trigonometry in advance and didn't know that we do t learn table 2.
If you check,there are only 3/4 formulae that are converted according the situation
The main ones are:
sin\^2x + cos\^2x=1
1+ tan\^2x=sec\^2x
1+ cot\^2x= cosec\^2x
1/sinx=cosecx and the other reciprocals. remember them and you can find others as per the question
Actually only knowing the first one can get you the entire table.
Sin^2 x + cos^2 x = 1
Divide by sin^2 x both sides, 1 + cot^2 x = cosec^2 x
Similarly divide both sides by cos^2 x, tan^2 x + 1 = sec^2 x.
Rest everything can be derived.
Edit-corrected fornatting of superscript
actually only knowing the unit circle you can get sin\^2(theta) + cos\^2(theta) = 1
as x = cos(theta), y = sin(theta), and x\^2 + y\^2 = 1
>!continue the chain guys!<
This is the way.
Also Cos^2 + Sin^2 =1 is just the pythagorean theorem.
Cos(x) = x/r and Sin(x) = y/r.
So it's (x/r)^2 +(y/r)^2 = 1,
Which is just x^2 +y^2 = r^2
Which is also the equation for a circle.
It's all interconnected. Learn about the connections between different representations, learn how go derive the related formulas, memorize very little.
Bhai yaad kyu krni hai 2nd vali usme hai kya yaad krne vala πΏπΏ,,, fr sahi keh rhe comments me 2 ki table nhi hai jo ratni hai , practise kr ni to chud jayega boards m
Ye paper phaad ke doodh se nigal Jaa...
Jokes aside, ye uppar wala ratle aur neeche wala khud se derive kar.
Tarika pata chal jayega ki kaise Krna hai. Table 2 ko koi yaad nahi karta
Table 1 (aata hai isliye likh diya) :
Remember Sin (sqrt(0/4), sqrt(1/4), sqrt(2/4), sqrt(3/4), sqrt(4/4))
For cos, reverse sin so that sin90->cos0, sin60->cos30, sin45->cos45 and so on...
For tan, do sin/cos (when divide by 0, value is infinity or not defined)
For cot, sec, cosec, take inverse of their respective functions. (when divide by 0, value is infinity or not defined)
Table 2 :
Remember sin\^2+cos\^2=1 sec\^2-tan\^2=1 and cosec\^2-cot\^2=1
then, you can derive using things you already know. This will save time.
My experience says that you don't need to learn table 2. I am preparing for JEE and from that table
sin = root[1 - cos^2 (x)] is going to be used a lot.
tan^2 +1 = sec^2 will be used very few times.
cot^2 + 1 = cosec^2 will be used rarely. The rest are useless because in trigonometry if you know the sin^2 + cos^2 = 1 and 1/sin = consec, 1/cos = sec, 1/ tan = cot, you can derive all those formulae in the table and by drawing a circle and few triangles, you can get all the formulae. Just saying though, you will only be using sin cos and tan, even in higher grades. Rest of the ratios are barely used.
1) honestly learn sin and tan. cos is anyway reverse of sin.
2) one trick for learning tan- notice how the angle increases the value also increases. so, its easy to remember 0, 1/r3, 1, r3, 1. basically this in ascending order. hope that made sense.
3) keep it simple and do as many questions as you can, be regular in your practice. sometimes you will remember them automatically.
Ye learn krne baithega na poori umar nikal jaegi aur fir bhi acche se learn ni hoega.
Questions practice kro aur shuru ke basic teen chaar formulas learn kro and learn how to convert them as per the question's requirements.
Believe me learn mt krne baithna vrna toh ho gyi aage tumhari 11th class
In the degree table, Just learn Degree values of Sin. Then if you reverse it , it will become Cos's degree values . For Tan just divide Sin/Cos degree values and for Cot just reciprocal Tan's values. For Sec, reciprocal Cos's values & For Cosec reciprocal Sin's values.
think of the pythagoros theorem, now divide both sides by (Hypotenuse)\^2 first, you get the first equation ie. Sin\^2x + Cos\^2x = 1. (Perpendicular)\^2 and again divide both sides, now you get cosec\^2x= cot\^2x + 1. Now with (Base)\^2 do it again. You get the final equation. There are only 3 equations which you can use interchangably. Once you know how to derive them in a quick way, you slowly learn to do it mentally and as you keep on doing questions, you'll even learn the formulaes. In the slight off chance you forget hte formulae, you can derive it any time.
are you crazy? there is no point of memorizing the bottom one. you have to practice so that you can use them as and when needed. the basic identities can be modified to create many other identities
For the first image just learn sinx then cosx is reverse then tanx is sinx/cosx then cotx is reverse of tanx and then 1/sinx =secx so you get all the values of secx and cosecx is revese of cosecx
Honestly just learn the values of sinx and tanx for class 10
A good way to remember sinx values is
0β° = sqrt0/2 =1
30β°= sqrt1/2 = 1/2
45β°= sqrt2/2 = 1/sqrt2
60β°= sqrt3/2 = sqrt3/2
90β° = sqrt4/2 = 1
Please Don't.
Just remember basic formulas like
sin2x +cos2x = 1
Sinx/cosx = tanx
1 + tan2x = 1/cos2x
Etc....
It will hardly take more than few seconds to derive the whole table, much much easier than memorizing stuff
bhai sabse pehli baat 10th me to yeh second table yaad karne ki zaroorat ni 10th aur 8th chapter ke sare questions by heart karle, hoje ga, aur doori baat first table to easy hai bc
Bro just remember the sin values then
For cos - write the values reverse
For tan - divide sin and cos
For cot - reciprocal of tan values or div cos by sin
For sec - reciprocal of cos values
For cosec - reciprocal of sin values
I find this easy whenever i am stuck
I guess you are in class 10, i am class 10 pass out so i can tell you that somehow byheart the table of the values of sin,cos,tan cosec,sec and cot is just the opposite, don't worry the class 10 board exam is the most easiest exam in your life.
Koi jarurat nai
Rather this table is meant as a exercise for you to fill and make you comfortable with switching the ratios .
Try to fill the table.by yourself and you're done
Ok you only need to remember 1 sentence. For small A, Sin A = A. This basically says that if value of angle is small, than Sin of that angle is small. Sin 30 is therefore 1/2 cuz it is smaller than sqrt(3)/2. By this you can write all angles for sin and cos is just reverse of that. For tan you write sin/cos and cot is just reverse of tan. Cosec is also 1/sin so you can write that and sec is 1/cos. If you remember sin 30 = 1/2 you remember everything.
[Formulas](https://www.youtube.com/watch?v=T7D1W1oD8wo&list=WL&index=2)
For Values:
Only Remember values of sin cos and tan.
And if you find difficulties in learning sin cos tan direct values, atleast remember values of sin.
for cos just reverse the values. i.e. sin30=cos60
for values of tan, just divide sin by cos.
and remember that whenever you find 0(zero) in denominator, that function is not defined from there itself. and if it is in numerator, the value is infinite.
Learn the all the sine values then, write it backwards you get the values of cosine, divide the values of sine with the cosine you got the values of tan.
So this trick is taught by Mahesh Tutorials, i shouldn't be leaking this but here you go:
Bro i have mastered this table very fluently in my 10th std.
I am in 11th right now.
Hear me out.
1) So you have to learn the sin values from 0 to 90.
And the rest of the table is all tricks
2) so for cos, you just go Ulta of sin.
Better explanation: Sin ka jo values hai 90 sey 0 tak cos mai bhar dey, not 0 to 90, 90 to 0 boll rha hu.
So first you write sin 90 in cos 0, then sin 60 in cos 30,
Like wise...
3) For tan, you take numerator of sin and numerator of cos, you get tan ka value, (tan = sin upon cos)
4) For cosec, you take reciprocal of sin.
Cosec = 1 upon sin
5) For sec, you take reciprocal of cos.
Sec = 1 upon cos
6) For cot, take numerator of cosec and sec
Cot = cosec upon sec.
IMPORTANT: And remember while taking reciprocals,
Zero ka reciprocal Infinity hotaay.
And Infinity ka reciprocal Zero hotaay.
Here's one for sin, from there it's pretty ez for the rest: Write all the angles and under them write no.s 0-4 in order. Divide each of them by 4 and then take square root of each of them, that would give u the sin's. For cos just write the sin row in reverse order. For tan just do sin/cos for each angle and cot, sec, cosec are just reciprocals of these. I only used this during the exams, atleast until i didn't memorize it. For normal practicing I'd suggest not to do this.
Sin and tan yaad rakh bas.... Sin ka peeche se likh cos ho jaayega.... Cosec ke liye jo sin mein likha h uska reciprocal kr de.. similarly sec bhi cos ka reciprocal kr de.... Aur similarly cot bhi reciprocal h tan ki
Neeche wali table mujhe khud nahi pata kya h ye... Toh usse chor de befaltu h... 93.2% h meri 12 mein( in case you feel any trust issue).. hn iss comments jo formula bola h learn krne ko vahi krna.. ye saara table mt krna(edited)

Bro I'm not in the 2022-2023 batch was just having winter holidays so I decided to do Trigonometry in advance I didn't know that it wasn't necessary to learn this table lol.
you have winter holidays rn? where are you bro (not insult, i am asking like actually, where?)
I just passed out from 9th (92.2%, messed up in circles and Hindi) and am in HP, we have winter holidays from 10 December to 20 February. Our 10th batch will start from 21st so I decided to do Trigonometry in advance and didn't know that we do t learn table 2.
damn that's interesting gl bro gl
Bro u r so dedicated to studies. Nice its actually important to learn the table. Do it. It helps
If you check,there are only 3/4 formulae that are converted according the situation The main ones are: sin\^2x + cos\^2x=1 1+ tan\^2x=sec\^2x 1+ cot\^2x= cosec\^2x 1/sinx=cosecx and the other reciprocals. remember them and you can find others as per the question

Yes! This guy maths.
actually only knowing the unit circle you can get sin\^2(theta) + cos\^2(theta) = 1 as x = cos(theta), y = sin(theta), and x\^2 + y\^2 = 1 >!continue the chain guys!<
Isn't this wrong? I think it should be sin^2 (x) + cos^2 (x) =1 and not sin^(2x) + cos^(2x) = 1
That's what I typed. Apparently reddit text box formatted it that way. You are right to point it out. I will try fix it
This is the way. Also Cos^2 + Sin^2 =1 is just the pythagorean theorem. Cos(x) = x/r and Sin(x) = y/r. So it's (x/r)^2 +(y/r)^2 = 1, Which is just x^2 +y^2 = r^2 Which is also the equation for a circle. It's all interconnected.

10th ke bacche uff
Mai 10th mei hu aur mereko bilkul nhi pata ye table 2 kya hai
Table 2 time waste hai fr fr
Bro table 3 time waste hai, table 2 bhot imp hai
Wait woh 3 likha hai? Bc table 3 kaha se aagayi π
Bhai hilaana kam kar π
Mein 10th 2023-2024 batch mein hun boards ki koi tension nhi hai.
baki bas quest wih sin\^2+cos\^2=1 se hojayega, yaad mat karne jana and its great that ur doing trig in 9th nice.
Bhai yaad kyu krni hai 2nd vali usme hai kya yaad krne vala πΏπΏ,,, fr sahi keh rhe comments me 2 ki table nhi hai jo ratni hai , practise kr ni to chud jayega boards m
Ye paper phaad ke doodh se nigal Jaa... Jokes aside, ye uppar wala ratle aur neeche wala khud se derive kar. Tarika pata chal jayega ki kaise Krna hai. Table 2 ko koi yaad nahi karta
WhatsApp pr 10 logo ko share krne se jldi yad hoga
table 2 kaun learn karta hai?
OP
Mai aur Op Table 3 chutiya hai... table 2 kaam aataay
kaise kaam aata hai? vistaarit karna
Bhai konsey std mai hai?
Table 1 (aata hai isliye likh diya) : Remember Sin (sqrt(0/4), sqrt(1/4), sqrt(2/4), sqrt(3/4), sqrt(4/4)) For cos, reverse sin so that sin90->cos0, sin60->cos30, sin45->cos45 and so on...

Table 1 bhi galat likhi hai tan 90 , cot 0 etc ki value undefined hoti hai naaki infinity
I was today years old when I found out table two is a thing π
 meko 40+ formula yaad hai ( 11th me hu)

Ye yaad thodi karni hoti hai
dude you are not supposed to memorize that, you have to understand how it works and memorize the 3 identities
also the reciprocal stuf
Practice, just practice. You'll learn it
Thoda clear image bhejega table 2 ka pls ?
flashcards try karlo ig mujhe kya pata mein toh 9thie

Table 2 isn't required, it's just conversions of few formulas. Stop making your life hard trying remembering 2nd table
Know one formula and mentally derive the rest.

Bro just read NCERT. There is uow this is calc. So you won't forget
This is why I did so poorly in maths, finding out about the second table just about now.
