if `intg(x)dx = g(x),` then `intg(x){f(x) + f'(x)}dx` is equal to

If int g(x)dx = g(x) , then int g(x){f(x) - f'(x)}dx is equal to

If intg(x)dx=g(x) , then int g(x)((x-1)/(1+x)^3)dx is equal to

Evaluate: if int g(x)dx=g(x), then int g(x){f(x)+f'(x)}dx

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

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

int (f'(x))/(f(x))dx is equal to-

If f and g are continuous functions in [0, 1] satisfying f(x) = f(a-x) and g(x) + g(a-x) = a , then int_(0)^(a)f(x)* g(x)dx is equal to
