Polar Sweep reinforces relationships between rectangular coordinates, polar coordinates, and basic trigonometry with a dynamic educational interface. Users can sweep through the circle to see changing values and helpful diagrams of right triangles for common angles.
Radians - as an introduction to radians this app shows decimal values, common PI fractions, and degree equivalents.
For a solid understanding of cartesian plane quadrants and polar coordinates, spend some time playing with this app.
Version 1.1: Now with a keypad for direct entry of (x,y) or (r, angle) coordinates, this app becomes one of the best rectangular-to-polar converters available.
