After sleeping on this, I suspect you need to add a design layer to your code with value procedures expressing Excel versions of all the AI2 trig blocks, for use with radians instead of degrees. (Excel trig tutorial: http://science.clemson.edu/physics/labs/tutorials/excel/trig.html) This would allow direct transliteration of the Excel formulas into AI2 formulas calling the new layer of value procedures. Here’s a package for you … [arccosine] [arcsine] [arctangent] [arctangent2] [blocks] […

Also, your block structure will be easier to check if you switch to external inputs (right click on the block.)

Export your blocks:
