### Cosine Taylor Series Solved on TI-89: Raw Transcript

Hello everyone this is Tom from every step calculus dot com

gonna do the Taylor series for Cosine of x

and let’s get started we have the index nine here to put in our

entry if the calculator to it to my menu

and we’re gonna

I’m gonna go up in get to the bottom of the alphabet and scroll up to to Taylor

Maclauren series

here it is here

and I tell you a little bit about the

parameters for instance when you enter 0 for

a in the formula and N the number of derivatives that you take

and of course one of the things for Taylor series and maclauren is that you know

you have to have repeating derivatives

here is the formula for the maclauren series

and for the Taylor series were going to enter our function we have to press alpha before you

enter anything in here

gonna go alpha and second cosine

of x close of the parentheses

and press enter and we’re gonna do it at

alpha, lets say 2

that’s centered at 2

here’s the Taylor series for you write that down here’s the first 5 derivatives

cosine of X and we’re doing it at the

X equals two here’s the answers there

write that on your paper we add the

factorials come up with these answers

write all this down exactly as you see it is important

here’s the answer

pretty neat huh.. every step calculus dot com go to my
