I'm doing a problem right now and I found the Maclaurin polynomial for it, but my professor wants us to find the remainder for every problem. Here is the problem:

Find the Maclaurin polynomial of degree *n *for the the function.

f(x) = xe^x where *n* = 4

I got the polynomial to be x + x^2 + 1/2 x^3 + 1/6 x^4. Now how do I find the remainder?
