Evaluate :
`( 1 + Sintheta )^2 - ( 1 - Sin^2theta )`

Evaluate : ( Sintheta + Costheta ) ( 1 - Sintheta Costheta ) = Sin^3theta + Cos^3theta

Evaluate : ( Cos^2theta - Sin^2theta ) / ( ( Costheta - Sintheta )^2

Evaluate : ( Cos^2theta - Sin^2theta ) / ( ( Costheta - Sintheta )^2

If costhetagtsinthetagt0 , then evaluate: int{log((1+sin2theta)/(1-sin2theta))^(cos2theta)+log((cos2theta)/(1+sin2theta))}d theta

If cot theta=(15)/(8), then Evaluate ((2+2sin theta)(1-sin theta))/((1+cos theta)(2-2cos theta))

Find the value of (sintheta)/(sqrt(1-sin^(2)theta))

Evaluate inttheta^(-(1)/(2)) sin theta^((1)/(2)) d theta.

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

For pi/2
