Evaluate `int (sintheta)/(cos^3theta) d theta`

int (sin theta + cos theta) * d theta

int(sin^(3)theta)/(sqrt(cos theta))d theta

" 7."int(sintheta)/((1+cos theta)^(2))d theta

Evaluate int((2 sin theta + sin 2 theta)d theta)/((cos theta-1)sqrt(cos theta + cos^(2) theta + cos^(3) theta)) .

Evaluate: int(1+costheta)/(theta+sintheta)d theta

Evaluate: intsin^3(theta/2)/(cos(theta/2)sqrt(cos^3theta+cos^2theta+costheta))d theta

Evaluate: int sqrt(tan theta)d theta

Evaluate: int cos2 theta ln((cos theta+sin theta)/(cos theta-sin theta))d theta

The value of (sin^3theta+cos^3theta)/(sintheta+costheta) +sin theta cos theta is:

If A= tan27theta - tantheta and B= (sintheta)/(cos 3theta) +(sin 3theta)/(cos 9theta) + (sin 9theta)/(cos 27theta) , then the value of (A+B)/(A-B) +(A-B)/(A+B) -10/3 is
