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.
I don’t know the answer to your question, but I recommend you look at the scoring guides for the released AP Calculus FRQ’S and see what the graders gave points for. That should help you answer your question!
I’m not sure what the CollegeBoard policy is, but I wouldn’t. Can’t you just stick to the boundaries of what’s being tested? Implicit is pretty straightforward (and doesn’t tend to appear on FRQ’s that much, anyway). I guess if you don’t know how to do it without multi, go for it, but otherwise stick to the boundaries of AP Calc.
