int cosec xdx=?

int cosec x dx = .................... .

Evalualte : int cosec^3xdx .

Evaluate: (i) int cot^2x cosec^4xdx (ii) int cosec^4xdx

intcotx cosec^2xdx=

int cosec^(4)xdx

int cosec^(2)xdx

If u=int cosec^(2)xdx , v=int cosec x cot xdx ,assuming the constant of integration to be zero then find u+v

int e^(cotx) cosec^2 xdx

int csc2ydy+int sec2xdx=0
