Hi,

Let me take the angle Thita as 'x'. So, given is that

Cosec x + Cot x = k,

To prove that : Cos x = k^2 - 1/k^2 +1

So take the given equation we have,.

1/sinx + cosx/sinx = k,

1+cosx/sinx = k, Now we use the formula that 1+cosx = 2cos^2(x/2) and sinx = 2sin(x/2).cos(x/2)

Hence k = cot(x/2)

put value of k in the proving equation,

(k^2 -1)/ (k^2 + 1) = cot^2(x/2)  - 1 / cot^2(x/2)

this gives , = cosec^2(x -2) / cosec^2 (x/2)

when you change it in terms of sinx and use the formula of cos2x = cos^2x - sin^2x , you will get the answer cosx.

Hope it helps.

Hello Pavan!

Let me tell you first about IISER exam pattern. IISER exam consists of 4 section: Physics, Chemistry, Mathematics and Biology. There are 15 questions asked from each section for the total duration of 3 hours of the exam. 3 marks are awarded for every right answer and 1 mark deducted for incorrect answer. No marks awarded or deducted for unattempted questions.

Now, it is not compulsory to attend math section, however, if you dont attend, then you will be loosing 15 marks for sure. So I suggest you to study math too. Join any coaching centre or if you can study on your own. There are several materials available online now.

All the best!

Hello Aspirant,

Please look at your query. What do you mean by spare? Did you intended to ask square?

Hello Aspirant,

I would request you to check your query again. We can calculate the area of a closed figure only, whether 2D or 3D. So please look into the query.
