Ok. Something else you could do would be using U-Substitution to disguise all of your work and drawings and then you could easily return to the main answer by restoring the equation of U to its initial state by plugging in and interchanging. It would be sneaky. People would think of you as a ninja or something. But it's not like it's Halloween. If it was Halloween you could just go as the derivative of e^x so you could go as yourself.
