”How exactly does this work? Can I somehow use sin(x)^2 + cos(x)^2 = 1 to my advantage? ”
Only if you are geodesist and need to count how much angle on ground is.... Or if you are military and need to count angle of fly of bullet.

How exactly does this work? Can I somehow use sin(x)^2 + cos(x)^2 = 1 to my advantage?
