I'm not that great and never have been in math, and to my misfortune, I am stuck with a Trigonometry "Teacher" that hasn't taught any form of math in 5-7 years until this year. And to make matters worse, I am in my senior year. All of my other grades are A's, but my Pre-Cal/Trig course grade is stuck in the 50%'s.
I found this site and right now I could use all the help I can get. Just an explanation would help at this point!

I'll do my best to help others with math as well (what math I understand).
