Somewhat Comprehensive Multivariable & Vector Calculus Formula Sheet
As a god-send from my MATH 217 professor this year, the class was permitted to bring in an 8.5 x 11 formula sheet to the final exam. As a result, I thought it would be a good learning experience to develop a rather comprehensive cheat sheet to, hopefully, infrequently reference during the exam.
