- X coordinate is returned correctly, but Y coordinate is returned as a negative when it should be positive. The equation for Y coordinate should be Y = x sin(θ) + y cos(θ). The problem with the Y coordinate equation is that the x coordinate is negative when it should be positive.

- This calculator is the rotation of "axes" calculator.

Please use the rotation of "points" calculator.
