 Calc Check
I have some concerns about the assumptions. I am especially not sure that the angle in the z plane is the same as that in the x plane. It seems to me that as the z plane moves, for instance if angle b and c were both 5° or both 40° the angle of d would be 45° however in the x plane the intersection of z’ and y’ would become more obtuse as the z plane approached vertical. At vertical d becomes 180, or a straigh line. |
