# College Calculus: Level II Taylor Polynomial Applications

Section 5: Taylor and Maclaurin Series: Lecture 2 | 50:50 min

In this lesson we are going to talk about applications of Taylor Polynomials. The idea here is that we are going to write down some Taylor Polynomials, and plug in some values of x and we will see how close we get to the original function values. We are going to see a couple of tests that we are going to be using to check how accurate we are. The first one is already mentioned previously - Alternating Series Error Bound. The second one is new and is called Taylor's Remainder Theorem. The whole idea will make more sense after we go through some examples.

For example 1, at 7:10 why did you compare the fraction to 1/100?

I am so lost here.

Please explain.

Thank you Professor Murray, I have enjoyed this course a lot. I have a question about this lecture. In examples 1 and 4, the wording of the problem asks about the Taylor polynomial for cos x, however in both solutions you use the Maclaurin expression that we memorized. In example 4 I assume this is because 1/2 is very near 0, so you choose a=0, am I right? But example 4 is more general, is it because the extension of the interval you find does not change with the value of a chosen or is there another reason?

On another subject, now that I have finished the Calculus II course, can I go to the Differential Equations course or should I do the Multivariable Calculus course first? I would appreciate your advise. Thank you.

Hello Dr. William Murray

Thanks for your patience for answering my questions in the previous lectures.

In example 5, the question asks us to use Taylor's Theorem, can the problem be done by the Alternating Series and the error be calculated by Alternating Series Error bound ?If so, which of the result will be more accurate or equally accurate?

Thanks very much.

This is the same thing as the Lagrange Error Bound right? Thanks by the way. My Calc BC exam is in a few days and I can't thank educator.com more for playing such a big role in my studying

Thank you for this amazing lecture series over CalcII!!! Do you know if there are any plans to incorporate any Engineering specific lectures in the near future such as statics, dynamics, fluids, etc.?

Thank you!

How did you ignore the rest of the function when estimating for -x^5? What would be the problem with leaving it as a positive number, as originally written? Why wasn't it x^-5 since it was in the denominator?
