Okay, so the instructions to the problem I have say, " Find the approximate values for each of the following integrals by applying the function simpleTrap" simpleTrap is explained here: Calculus I and II - Lab 17 So I have the problem: $\displaystyle \int_{0}^{2} e^xdx$ in mathematica I get 8.38906, but on my calculator it says 6.38906, which is correct?

This is what I put in for mathematica:

In[6]:= f[x_] := E^x

In[7]:= N[(2 - 0)*(f[0] + f[2])/2]

Out[7]= 8.38906

Thanks,

Matt
