Evaluate: `int(P+Q)dx`

Evaluate: int dx

Evaluate: int(dx)/((x-p)sqrt((x-p)(x-q)))

Evaluate int logx dx

Evaluate: int(1)/(p+q tan x)dx

Evaluate : int sec^p x tan x dx

Evaluate : int sec^p x tan x dx

If u and v are two functions of x then prove that : int uv dx = u int v dx - int [ (du)/(dx) int v dx ] dx Hence, evaluate int x e^(x) dx

Evaluate : int ( cosecx ) dx
