    Definite Integral

    It is an explanation for finding the integral by using the method of summation(part I).

    Find by the method of summation the value of:

    (a) ∫ e^( - x)dx, where the lower limit is a and the upper limit is b,
    i.e., integral of e^( - x), where the lower limit is a and the upper limit is b.
    (b) ∫ e^( kx)dx, where the lower limit is a and the upper limit is b,
    i.e., integral of e^( kx), where the lower limit is a and the upper limit is b.
