You could also try local linear approximation: f(x)\sim f(a)+f^\prime (x)\cdot (x-a) which in this case would boil down to computing 1+2\sin ({{e^2 \pi}\over {2}} ) since your possible answers are all fairly different (hindsight: the correct answer is very different from the others)...

With the caveat that I have not actually studied much financial math, I recommend that you start with some work in probability and combinatorics. If you are comfortable with calculus, you will pick it up easily enough, and I think it will come in handy as your studies focus on wherever your...

Can you be more specific about what you are trying to do? If you were to choose a basis for the space of fourth degree polynomials, like \{ 1,x,x^2,x^3,x^4 \} , then it is possible to represent a polynomial as an element of this vector space by a coefficient matrix. For example...
