int cot^(4)theta d theta

Evaluate the following integrals : int cot^(2) theta d theta

The value of int_(pi//4)^(pi//2) cot theta cosec^(2) theta d theta is

int_(0)^((pi)/(4))theta sec^(2)theta d theta

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

Evaluate int _(0)^(pi//2) (cos^(4) theta)/(sin^(4) theta + cos^(4) theta)d theta

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

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

int sin^4 theta d theta

If theta=9^@ , then what is the value of cot theta cot2 theta cot3 theta cot4 theta cot5 theta cot6 theta cot7 theta cot8 theta cot9 theta ? यदि theta=9^@ ,तो cot theta cot2 theta cot3 theta cot4 theta cot5 theta cot6 theta cot7 theta cot8 theta cot9 theta का मान क्या होगा?

int(cosec theta-cot theta)/(cosectheta+ cot theta)d theta=
