First of all, am i right in saying this can also be called a Maclaurin series, since we're considering it around x = 0?
And, secondly...well, not really sure where to begin, or how to phrase my answer, I can see why it would be true from the info given..but having difficulty putting it into the correct form...
If anyone can help, it would be greatly appreciated.
