Note: All of the geometry and trigonometry solvers in this app are also in my 179-in-1 Math Calculator app. Do NOT purchase 39-in-1 Geometry and Trigonometry Calculator if you already own that app.

With this app, you get 39 solvers (actual calculators, not formulas) on topics in geometry and trigonometry.

Features:
- 39 solvers covering geometry and trigonometry
- Add a solver to your favorites with just one tap
- Edit and organize your favorites list from the “Favorites” tab
- See your most recently viewed solvers from the “Recents” tab
- Check out your most viewed solvers from the “Most Viewed” tab
- Request solvers or send comments in-app using the “Contact Us” tab.
