Suppose we wanted to find a fourth degree polynomial of the form: that approximates the behavior of at If we make , and the first, second, third and fourth derivatives the same, then we would have a pretty good approximation.

If we plot both functions, we see that near zero the functions match very well!

Our polynomial: has the form: This pattern occurs no matter what the original function was! or:

Maclaurin Series: (generated by f at ) If we want to center the series (and it’s graph) at some point other than zero, we get the Taylor Series: Taylor Series: (generated by f at )

example:

The more terms we add, the better our approximation. Hint: On the TI-89, the factorial symbol is:

example: Rather than start from scratch, we can use the function that we already know:

example:

There are some Maclaurin series that occur often enough that they should be memorized. They are on your formula sheet.

When referring to Taylor polynomials, we can talk about number of terms, order or degree. This is a polynomial in 3 terms. It is a 4th order Taylor polynomial, because it was found using the 4th derivative. It is also a 4th degree polynomial, because x is raised to the 4th power. The 3rd order polynomial for is , but it is degree 2. The x3 term drops out when using the third derivative. A recent AP exam required the student to know the difference between order and degree. This is also the 2nd order polynomial.
