While attending the prestigious ASU Math-Science Honors Program a student scribbled in his test booklet an answer that is supposedly true in quasi-static quantum singularities;

If f(x)=e^2x + e^-2x, then in n-dimensional subspaces of a 12-dimensional multi-versus the derivative of f(x) is as follows;
f'(x)=0.

But... we don't exist in singularities, so the answer was marked wrong.
