Trigonometry

great when you are very lazy...(like me)

Sweet sugary goodness... this app rocks. I'd been having trouble in PreCalc understanding all the relations between radians, degrees, sines, and all that nasty stuff. Being a visual hands-on learner, this has helped tremendously in understanding trig. Other features I'd love to see in the future would the ability to show and calculate tangents/cotangents, secants/cosecants, and copy and export functions to place graphs into other docs. The app did spaz out and lock (i.e., spinning beachball) the first couple times I opened it. It seems to be fine now, though. Bizarre, whatever it was, but it works now. :)

Nice app. Maybe the author could add more features, like "arc" and "tan". And why not some complex functions too ?
