hey what u do.....
substitute the sin2 theta as 1 - cos2 theta .........
then shift the 1 to the RHS and subtract 1 frm 1 ....it will give
sin theta - cos2 theta = 0
after u get cos2 theta = sin theta.....
thus substitute cos2 theta in the above equation ....u will get ur answer

I CANT UNDERSTAND
it is correct friend
u just substitute sin square theta as 1-cos square theta....and solve u will get the answer
I CANT UNDERSTAND
