Purpose of use
Calculating the Angles of the Frame for a Grid of Solar Panels on a Pitched Roof.
Needed the roof pitch,
then the Solar panel angle,
then the frame angles to match the two figures to the required Sun Angle.

Got enough angles and calculations there? lol

With this help, I got everything to fit Correctly the First time!
