Out of all the math classes I have ever taken, Algebra and Trigonometry are the only classes I ever gotten an A in. But the reason as to why Algebra is the only one I am willing to teach is because I took it recently and it is fresh in my mind. I haven’t done a Trigonometry problem in years.
Granted, I’m pretty sure I could relearn Trig. If you have any questions on the matter, just let me know via comment. I’ll see if I can help. 😀
