I'm currently in college and taking trigonometry this summer after not taking any math classes in 2 years (since high school). I was always pretty good in math in high school. But two years of doing literally no math is a long time. I can't remember anything. I'm afraid of doing a summer course of trig and basically just being dumbfounded.

Does anyone have any advice or resources I can use to catch up again?

Student here. Thinking about dropping my Trig class this summer. One week in and we've already covered five sections and the first test is today, we only meet two times a week.

I've got some stuff down but I work and have another class. I already know I'm going to bomb the test if I can't have my notes out.

Should I drop before it's too late? Today is the last day for refund.

So heres the thing. I could swear that my math teacher back in high school has this thing he called the Trig wheel. It wasn't a circle with the angles and radians labeled, it showed the actual functions and identities. It was like a jew-star with a 1 in the center. Wanna help a bro out?

Can someone give a fast break down of trig?
