    I can't find this integral

    For some reason, I can't remember how to do the integral of f(x).


    I don't see F(a)-F(b) giving me any results. thanks for the help.

    The integral is nothing more than AREA under a curve. Integration is useful, because most graphs do not have nice straight lines and can't be solved using known formulas for areas of geometric shapes. This however, is a function with nice straight lines.

    ALso, using F(a)-F(b) isn't any help because you don't know what the anti-derivative is; of course you don't need it in this instance.

    Count the squares with due regard for signs
