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
