" (iv) cosec "x

Write down the integral of the following (i) sinx+cos x (ii) cosec x (cosec x + cot x)

cosec x =-2

cosec x =-2

Evalute the following integrals int ("cosec "x)/("cosec" x - cotx") dx

Find int "cosec"x ( "cosec" x + cot x ) dx

int e^(-x) cosec x(1+ cot x) dx is equal to a) e^(-x) cosec x + C b) -e^(-x) cosec x + C c) - e^(-x) ( cosec x + cot x ) + C d) - e^(-x) ( cosec x - tan x ) + C

Evaluate : int"cosec"x("cosec "x-cotx)dx.
