यदि `sin theta =3/5` तथा `(pi)/(2) lt theta lt pi` तो `cos theta` का मान है

sintheta = (3)/5 , (pi)/2 lt theta lt pi sin2theta = (-12)/25

If sin theta =12/13 ,(pi)/(2) lt theta lt pi find the value of sec theta + tan theta

sin 2theta = cos 3theta (0 lt theta lt pi)

If sin theta = 4//5, where pi//2 lt theta lt pi, evaluate : (sec theta + tan theta)/(cosec theta - cot theta)

If 3 sin 2 theta=2 sin 3 theta and 0 lt theta lt pi then sin theta=

If 3 sin 2 theta = 2 sin 3 theta and 0 lt theta lt pi , then sin theta =

If 3 sin 2 theta = 2 sin 3 theta and 0 lt theta lt pi , then sin theta =
