Test Pythagorean Theorem on Both Sets Fu = sind(40)*500/sind(119) Fv = sind(21)*500/sind(119) Fx = 500*cosd(38) Fy = 500*sind(38) MagFxy = sqrt(Fx^2+Fy^2) MagFuv = sqrt(Fu^2+Fv^2) Fu = 367.4669 Fv = 204.8707 Fx = 394.0054 Fy = 307.8307 MagFxy = 500 MagFuv = 420.7184 Since the uv Basis is NOT OrthoGonal, then Pythagorus does NOT hold
