Considering the complexity of the correct answer, I wonder how many people actually got that correct.

Honestly it depends on what the question was. For instance if the question was "write this integral in the form of a sum" it might not be so bad

There are still a lot of rather arbitrary decisions to make.

Is 4/pi inside or outside of the summation?

Is it (-1)^n+1 or (-1)^n with an additional negative sign in any of the other natural locations for it.

Is the e term outside of the fraction with a negative exponent, or part of the denominator.

Do you start with n=0 or n=1 (and adjust the terms inside the summation accordingly)

Did they expand (2n+1)^2?
