Question

find the value???????????????????

Answer 1

Hey mate!

Here's your answer!

Let us arrange the equation in the following manner.
sin^2Acos^2B + cos^2Acos^2B + cos^2Asin^2B + sin^2Asin^2B
=> cos^2B(sin^2A+cos^2A) + sin^2B(cos^2A+sin^2A)
=> cos^2B(1) + sin^2B(1) [Since sin^2x+cos^2x = 1]
=> cos^2B + sin^2B
=> 1.

Hope it helps :)
