Question

Solve this :-
(cos^2 A-1)(1+cot^2 A)=-1​

Answer 1

Answer:

Taking L.H.S

(cos^2A - 1)(1+cot^2A)

[-(-cos^2A + 1)] (cosec^2A) { {1+cot^2A=cosec^2 A}

[-(1-cos^A)] (cosec^2A)

-sin^2A . cosec^2A {1-cos^2A=sin^2A}

-1 {sin^2Acosec^2A=1}

Answer 2

cos squared minus 1 into 1 + cos square is equal to cos square A + cos square into cot square A minus 1 minus cot square A is equal to cos square A minus cos square A into sin square A + cos square into cos square A by sin square A minus one is equal to sin square A cos square A minus cos square A + cos to the power 4 minus sin square A upon sin square A is equal to cos square A minus 1 by sin square A is equal to minus 1....♥️♥️
