`int(dx)/((1-cot x))`

int (x)/(1-x cot x)dx=

int(dx)/(1+cot^(2)x)

int_(0)^( pi/2)(dx)/(1+cot x)

Evaluate: ( i int(cos x)/(1-cos x)dx or int(cot x)/(csc x-cot x)dx (ii) int(cos^(2)x-sin^(2)x)/(sqrt(1+cos4x))dx

int(dx)/(cot((x)/(2))*cot((x)/(3))*cot((x)/(6)))

int(dx)/(cot((x)/(2))*cot((x)/(3))*cot((x)/(6)))

Integrate int(1)/(1+cot x)dx

int(tan x)/(cot x)dx

Evaluate :int_((pi)/(6))^(3)(dx)/(1+sqrt(cot x))

int_(0)^((pi)/(2))(dx)/(1+cot x)
