    Does this help?

    [tex]\int_a^b = \int_a^0+ \int_0^b[/tex]

    [tex]\frac {d}{dx} \int_0^x f(x') dx' = f(x)[/tex]

    a. Use the additive property of definite integral.

    [tex]\int _0^bf(t)dt=\int_0^af(t)dt+\int_a^bf(t)dt [/tex]

    b. Remember that the differential quotient of definite integral with respect to the upper bound is the integrand itself.

    [tex] \big[\int _0^xf(t)dt\big]' = f(x)[/tex]
