SUMMARY
The discussion clarifies the calculation of angles related to the motion of an electron in an electric field. The user initially attempted to use the formula tan(x) = sy/sx, which represents the angle between two points A and B. However, the correct approach is to use tan(x) = vy/vx, which reflects the angle of velocity at point B. The distinction between the angle of the trajectory and the angle of velocity is critical, as they yield different results, confirming that tan(θs) ≠ tan(θv).
