Evaluate this formula for using the power series expansion for f at q = 0:
I have two questions.
1.) Is this power series expansion correct? I tried inputting this function in MATLAB and it gives me a different power series expansion:
2. Regarding the power series which is defined as
at q = a.
Since this power series (1) I do not understand how a power series can be derived this way since at q = 0, then f(0) from (*) is undefined because we can not divide by 0, correct?
Thank you for reading.
