WebThe Maclaurin series expansion for xe^x is very easy to derive. This is one of the easiest ones to do because the derivatives are very easy to find. All you have to do is to find the derivatives, and their values when x = 0. Then substitute them into the general formula shown above. When x = 0, xe^x = 0 because anything multiplied by 0 is 0.
