int(2sin theta cos theta)/(sin^(4)theta+cos^(4)theta)d theta

int (cos^(4)theta )/("sin" theta)d theta

Find :int(cos theta)/((4+sin^(2)theta)(5-4cos^(2)theta))d theta

I=int_(0)^( pi/4)(sin2 theta)/(sin^(2)theta+cos^(4)theta)d theta

int sin^4 theta d theta

If sin theta+cos theta=a, then sin^(4)theta+cos^(4)theta=

int (sin theta + cos theta) * d theta

The value of (cos^6 theta+sin^6 theta+ 3sin^2 theta cos^2 theta)/(cosec theta sec theta(sin theta+cos theta-1)(sin theta+cos theta+1)) is : (cos^6 theta+sin^6 theta+ 3sin^2 theta cos^2 theta)/(cosec theta sec theta(sin theta+cos theta-1)(sin theta+cos theta+1)) का मान ज्ञात कीजिए?

int (d theta)/((sin theta - 2 cos theta)(2 sin theta + cos theta))

int (d theta)/((sin theta - 2 cos theta)(2 sin theta + cos theta))
