So currently I'm taking AP Calculus and Calculus II at UPENN (which I assume is like calculus III in other colleges). I was wondering if the people grading the tests would give me credit, especially on the FRQ's for work, if I use multivariable calculus stuff. I mean, there are severable instances where some theorems come in handier than the way we're taught in ap calculus. Like implicit differentiation can easily be done by the formula dy/dx = -Fx/Fy by partials, etc. o.O Cause I don't want to be getting correct answers but not getting credit for showing work.
