Question

(sinA - sinB / cosA + cosB) + (cosA - cosB / sinA + sinB) = 0

Answer 1

Hiiiii .....

Cross multiply the eqn .....

(sinA - sinB)(sinA + sinB) + ( cosA - CosB )(cosA + cosB ) / (cosA + cosB)( sinA + sinB)
......
= (sin^2A - sin^2B) + (cos^2A - cos^2B ) / (cosA + cosB)( sinA + sinB) ...

= 0 .....
As (sin^2A + sin^2B =1)..........

Answer 2

Here's your answer...

Have a good day ✌
