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.

WebMay 31, 2016 · n! is the factorial of each index n. Like I mentioned earlier, for a Maclaurin series, a = 0. So, first let's take four derivatives of sin(3x2), since this will take a lot of product rule and chain rule maneuvering. Recall that sin is cyclic after four derivatives ( sin → cos → − sin → −cos → sin ). We can plug in a = 0 later. WebSin3x. Sin3x gives the value of the sine trigonometric function for triple angle.
