Question

1-sin^2A/1-cos^2A= what is the answer for this question​

Answer 1

Answer:

Step-by-step explanation:

Given that,

1 - sin^2 A / 1 - cos^2 A

we know that sin^2 A + cos ^2 A = 1

So, 1 - sin^2 A = cos^2 A and 1 - cos^2 A = sin^2 A.

Hence , 1 - sin^2 A / 1 - cos ^2 A = cos^2 A / sin^2 A = cot^2 A is the answer.

( Since , cos A / sin A = cot A. )
