Expand the function into Maclaurin series on the whole real line .
So here is what I have done so far:
From what I have been able to figure out, though I am not sure this is correct, the Maclaurin series is defined as
.
I solved for .
Similarly, , giving .
Once again, , giving .
Is the right direction? Should I be finding some pattern here? What is the final answer supposed to look like?
