# Does Calculus help with SAT I Math and SAT II Math 2?

Math II I'd imagine it would be a huge help, with all my newfound fancy limit knowledge I didn't know before. During a practice test I forgot how to find the vertex of a parabola so I set the derivative equal to zero to get it, was pretty proud of that. SAT I Math, I doubt it would help at all.

Does anyone else have testimonies of using Calculus in these?

A similar scenario I've seen occurred when I had to find the minimum value of x + (1/x) (or something like that, idr) where x > 0. You can do this with calculus without too much effort, but AM-GM gives a slick, one-second solution, giving x = 1 as the value that minimizes x + 1/x.

Couldn't you just use a graphing calculator to solve both those problems? Less chance for error and it doesn't take that long.
