Calculate the first 5 terms of the taylor expansion of e^x about x=0.
Use the first four terms of the above expansion to approximate e^0.5. Answer to 6 d.p.
Finally, use the final term to estimate the error in your approximation. Answer to 3 sig figures.

Alright, well the Taylor series expansion for a function f(x) about the point x = a is given by:
So in your case,
and
.
so using the above formula, the first two terms are:
And you can find the remaining three in that same way...
