Coordinates Calculator - Convert Coordinate Systems

Convert points between Cartesian (x, y) and Polar (r, theta) coordinate systems using trigonometric relationships.

1. 1

   Step 1

   Select conversion direction

2. 2

   Step 2

   Enter coordinates in the source system

3. 3

   Step 3

   Choose angle unit (degrees or radians)

4. 4

   Step 4

   View converted coordinates

• 1

  Cartesian coordinates are named after Descartes

• 2

  360 degrees = 2 pi radians

• 3

  The polar system is useful for circular shapes and rotational motion

• 4

  Pay attention to the quadrant when calculating angles

• 5

  The Cartesian point (0,0) corresponds to r=0 in polar

• Forgetting to convert angles between degrees and radians

• Not paying attention to the correct quadrant when calculating the angle

• Confusing sin and cos in conversion formulas

• Entering a negative value for the radius r
