The basic structure of the formula for calculating angles is the same in all cases: 1) LINE - LINE: You select the direction vectors of the lines and apply the formula for calculating angles to them. Caution: You must also include the scalar product in the absolute value, as we always want to create the smaller angle. 2) PLANE - PLANE: You select the normal vectors of the planes and apply the formula for calculating the angle to them. The rest is the same as in (1). 3) LINE - PLANE: You select the direction vector of the line and the normal vector of the plane and apply the formula for calculating the angle to these two vectors – only not with cos to the power of -1, but with sin to the power of -1. This is because the normal vector has been rotated by 90°, and because we want to take this into account, we have to think back through the rotation – cos to the power of -1 becomes sin to the power of -1. --------MORE VIDEOS FOR YOU------------------- ...I'll post them here as soon as they're uploaded :)
