    Man, I wish I knew about this over the last 2 years of calculus! Even after 10 minutes with the app, I understand trig a little better. I think the function values tab computer. I'm definitely jumping to this next time I need a trig reference.

    This is quite interesting. Is there a reason why the quadrants have the 2nd and 4th quadrants as in app?

    useful, indeed. but hangs everytime I go to the other sections of the app. also, the background sucks...the screenshot previews provided here in googleplay is a lot better imo
