Result data

FormulaLeft = Math.cos((pan+1)*Math.PI/4); Right = Math.sin((pan+1)*Math.PI/4)

Made for real tasks

Load the example in the workspace to reproduce these results. Display rounding does not change the underlying calculation.

Enter pan.
Use consistent units shown beside each input. Run the calculation and review the assumptions below.
