Answer 2

how do i start?

Answer 3

Well c is a constant that can be factored out of the integral until the end. Then you're just left with integral dx. Well, integral dx is just x. If you integrate and have x with limits from a to b, do you know how to plug that in?

Answer 4

i know that..but i have to use the definition of integration..

Answer 5

\[\int\limits_a^b c \, dx=c (b-a) \]

Answer 6

\[\int\limits_{a}^{b}f(x)dx = F(b)-F(a)\]
