Helpful for understanding Trig
My Geometry teacher decided to introduce my class to Trig, and..it went terribly, at least for me. He wasnt really a good teacher, as Trig confused the heck out of me. It still does, but thanks to this app, I understand it a little better. Though Im still kinda confused because my teacher used degrees and not radians, while this guy seems to like radians.
