Sin theta=( a+b)/(a-b) find tan^2 theta

Answer»

Step-by-step EXPLANATION:

sin THETA = (a+b)/(a-b)

sin²theta = (a+b)²/(a-b)²

1-cos²theta = sin²theta = (a+b)²/(a-b)²

By solving , we GET cos²theta = -4AB/(a-b)²

tan²theta = sin²theta/cos²theta

= {(a+b)²/(a-b)²}/{-4ab/(a-b)²}

= (a+b)²/-4ab

= -(a+b)²/4ab
