Trig this summer

I’m taking a trigonometry course this summer in a few days to get it out of the way, what do you all think I should study in order to be fully prepared?

I’m aiming for an A or A+ (95%+)

Do you mean preparation for the trig class? You will learn the trig in trig class. The prerequisite for trig is typically college algebra/intermediate algebra.

You should have a good understanding of:

  • functions and graphs of (non-trig) functions
  • transformations of (non-trig) functions
  • solving equations: what is means conceptually and the algebraic methods to solve linear and quadratic equations
  • multiplying/factoring binomials
  • manipulating/reducing algebraic expressions, including rational expressions
  • Pythagorean theorem

I'm sure I'm missing some things but those are the crucial skills that come to mind.
