I am finally getting my feet wet, actually taking math courses that apply to my degree. Anyone have any suggestion what I should be studying before I take the class? I have borrowed a book from a local library called "Calculus Essentials for Dummies." I have a friend who is in calc 3, I think. He recommend I memorize the unit circle and trig identities. I am supper stoked! I can't wait to take this class!
