int x cosec^(2)axdx

int x cos ec^(2)axdx

Integrate: int x "cosec"^(2) x dx .

We can derive different reduction formulas by using integration by parts. If int cosec^(n)x dx=(-cosec^(n-2)x cotx)/(n-1)+A int cosec^(n-2)x dx , then A is equal to-

int e^cot x cosec^2xdx

int cotx cosec^2x dx

int sec^(2) x cosec^(2) x dx

Evaluate: int x^(3)cosec^(2)x^(4)dx

int (1-cot x)cosec^(2) x dx equals :

int cot^(3) x. cosec^(2) x dx
