Just a question for you. How do you remember all this. I'm wondering because I'm in precalc and I always seem to forget how to do the problems a couple weeks after the test. You seem to know everything without even hesitating.

Side note- I found this site by googling a math problem. I saw your response on a bearings question which I've been struggling to figure out.

I'll be using this a lot in the future since I have a teacher that doesn't teach material, she merely assigns work or puts irrelevant material on her tests that we were never taught.

Well Dustin, after teaching this stuff for about 35 years, it becomes part of your "permanent memory". I have been retired for 17 years and I try to keep my mind active doing this voluntary tutoring.

I taught in Ontario, all grade levels and all math courses, but mainly Calculus.
I am getting a bit rusty with integral Calculus, and some of the new statistical methods sometimes baffle me. (never had a great liking for stats)

Glad to have you onboard.
