Hello, a question on my homework is in this form:
f(x) = 1/X about Xo = 3. (Xo is x naught, btw)
I'm confused what "about x naught" means, because the form I've been shown in class is about a, aka, the series:
Sum from 0 to infinity of Cn(X-a)^n
is called a power series about. Does x naught take the place of a, or do I use it to find the first term (since the power n would be 0) and therefore the c value, or some other way?
If you know what my prof means by this it would be wonderful.
