Question

pls solve this question guyzz I'll give uhh brain mark plz ​

Answer 1

Answer:

Step-by-step explanation:

Prove that

4(cot^-13+ cosec^-1 √5) = π

To prove, 4( cot-1 3 + cosec-1 √5) = π

So, to prove, cot-1 3 + cosec-1 √5 = π/4

L.H.S. cot-1 3 + cosec-1 √5 = tan-1 1/3 + tan-1 1/2

= tan-1 [(1/3+1/2) / (1-1/6)] = tan-1[(5/6)/(5/6)]

= tan-1(1) = π/4 = R.H.S.

Hope it helps..!!

Good luck for future..!!

Please mark it as brilliant..!!
