mathematica is correct ... using the geometry formula for a simple trapezoid ...
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: 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:= f[x_] := E^x
In:= N[(2 - 0)*(f + f)/2]
