@copper.hat Apologies if I'm not clear. The phrasing the book uses suggests that there is a general proof that $e^x$ can be expressed as a series

@Alex Just checked on wikipedia. The definition in the question is correct(?) en.wikipedia.org/wiki/Exponential_function#Formal_definition

@AlexR Well I have to say, this is the first time two of my errors have cancelled each other out. I wish it would happen more often... Thank you both for your help :)

comment Finding the coefficient of $x^{10}$
I thought this might be the case. I was going to multiply out with the $x^{10}$ but the word "hence" threw me. Thought I would check with people better at maths than me. Thanks for your help.
