`int {f(x) pm g(x)} dx = int f(x) dx pm int g(x) dx`

int{f(x)+-g(x)}dx=int f(x)dx+-int g(x)dx

int f(x) dx = g(x) , then int f(x)g(x) dx =

Show that int_0^a f(x)g(x)dx = 2 int_0^a f(x)dx , if f and g are defined as f(x) = f(a-x) and g(x) + g(a-x) = 4

If int f (x) dx = g (x) +c, then int f(x)g' (x)dx

int e^x {f(x)-f'(x)}dx= phi(x) , then int e^x f(x) dx is

If int f(x)dx=g(x) then int f^(-1)(x)dx is
