Maclaurin polynomials
Find the Maclaurin polynomials of orders n = 0, 1, 2, 3, and 4, and then find the nth Maclaurin polynomials for the function in sigma notation.

1)sinh x

2)xe^x

3)ln(1+x)

4)cos PIx

The formula for the nth Maclaurin polynomial is $f(x) \approx \sum_{k=0}^n\frac{1}{k!}f^{(k)}(0)x^k$ where $f^{(k)}(0)$ is the kth derivative of f at x=0.
