Law of Sines and Cosines Free for Android
Great help for making sample problems. Just input the given, and they'll compute the missing parts.
When I was in trig this app saved my life. Trying to find answers on paper was almost impossible for some things, but this app gives you the answers AND how to come up with them. So yes, it is cheating, but you can still learn from the app as to how to actually solve the problem. Great app!
