can anyone help me with these 3 questions Use the fundamental theorem of calculus to show that: a<b b a int f(x)dx = int f(x)dx a b b b int kf(x)dx = Kintf(x)dx a a a<c<b c b b intf(x)dx+intf(x)dx = intf(x)dx a c a

I cant get the a's and b's to line up. They should be over the int's (for integral)

If F'(x)=f(x) then: a ∫f(x)dx=F(a)F(b) b This should solve all of them!
