Question

sin2theta(1/1-cos theta+1/1+cos theta)=2​

Answer 1

Answer:

sin^2 theta (1/1-cos theta +1/ 1+ cos theta ) =2

LHS

sin^2theta ( 1+ cos theta +1 - cos theta / (1-cos theta ) ( 1+ cos theta)

sin^2 theta 2/1-cos^2 theta

( a+b) (a-b) = a^2 - b^2)

1-COS^2 theta X 2/1-cos^2 theta

2 .

hence LHS=RHS
