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

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

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

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

Evaluate: (i) int(1)/(e^(x)+1)dx (ii) int(cot x)/(log sin x)dx

Evaluate the following inte^x(1-cot x+cot^2x)dx

Evaluate the following inte^x(1-cot x+cot^2x)dx

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