Example Question #11 : Taylor And Maclaurin Series
Write out the first four terms of the Taylor series about for the following function:
The Taylor series about x=a for a function is
For the first four terms (n=0, 1, 2, 3), we must find the zeroth, first, second, and third derivative of the function. The zeroth derivative is the function itself.
The derivatives were found using the following rule:
Now, use the above formula to write out the first four terms:
which simplified becomes
