# New coordinates by rotation of axes Calculator

## Calculates the new coordinates by rotation of axes. | ||

- Purpose of use
- force rotations
- Comment/Request
- Rotation angle is backwards. The X,Y equations listed are for CW rotations but the calculator tells you to define CCW as positive. The vector (1,0) rotated +90 deg CCW is (0,1). This calculator will tell you it's (0,-1) when you rotate by +90 deg and (0,1) when rotated by -90 deg.

You must use positive angles or CW or negative angles for CCW for the correct answer (opposite of what it says to do).
