`Sintheta + 1/Sintheta = 4`
`Sin^2theta + 1/Sin^2theta = ?` , evaluate this expression

Sintheta - costheta = 0 Show : Sin^4theta + cos^4theta = 1/2

Find the range of 12sintheta-9sin^2theta

If sintheta - costheta = 0 , then sin^4theta - cos^4theta = ?

Solve: sin4theta=sintheta

sin.theta. cosec theta= …..

sintheta+sin7theta=sin4theta

Evaluate : a Sin^3theta Costheta + a Sintheta Cos^3theta

Evaluate : ( Sin^3theta + Cos^3theta )/ ( Sintheta + Costheta )

If sintheta+costheta=1 , then the value of sin2theta is

Evaluate : ( Cos^3theta + Sin^3theta ) / ( Costheta + Sintheta ) + ( Cos^3theta - Sin^3theta ) / ( Costheta - Sintheta )
