Question

If f(0)=g(0)=0 and f'' and g'' are continuous, show that
∫ f(x)g"(x)dx= f(a)g(a) + ∫ f"(x)g(x)dx
upperbound is a and lower bound is 0

Answer 1

ok this is simple i will solve it for u

Answer 2

ok

Answer 3

i am solving some other problem so just be a bit patient but for the sake of solution we are going to use integration by parts

Answer 4

I solved it already used integration by parts twice
