    How do I plot the derivative of a curve in Excel?

    Hello,
    I am working on a maths project and I need to plot the derivative of an
    exponential curve, however, (as far as I know) there is no function that is
    capable of differentiating an exponential function. I hope somebody can help
    me.

    Thanks in Advance,

    Rients.

    If f(x)=exp(g(x)), then, by chain rule, f'(x)=g'(x)*exp(g(x)).

    Then, to plot the derivative, set up a table in Excel with the necessary values/formulas:
    x, f(x), f'(x)

    Then plot using an XY scatter plot.
