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

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

int(1)/(cos x . cot x ) dx

Evaluate: int(8cot x+1)/(3cot x+2)dx

If (cot x+(cot^(2)x)/(2)+(cot^(3)x)/(3)+...+(cot^(99)x)/(99))+ int(1+cot x)(1+cot^(99)x)dx =-lambda[int cot^(2)xdx+int cot^(3)xdx+int cot^(4)xdx+...+int cot^(98)xdx] , then value of lambda is equal to

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

Evaluate: (i) int(tan x+cot x)^(2)dx (ii) int(1-cos2x)/(1+cos2x)dx

int(tan x)/(cot x)dx

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

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

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