If the angles around the on-axis angle have a similarly smooth response, then it isn’t as critical that the speaker is listened to with ears at the same level. Diagonal view of a waterfall plot ...

Now, the dot product of N and (0,0,1) should be the cosine of the angle between the two vectors. Formulas for both the dot and cross product of 3d vectors are easily found.

CASTER. Understanding steering axis inclination makes it easier to understand caster, since they both have somewhat the same effect. Caster is the angle formed by a line through the ball joint ...

The ebb and flow of seasonal change is linked to the angle of the planet’s rotational axis, and over geologic time, a wandering axis could affect climate on a global scale, said Surendra ...

A highly directional speaker is one where the sound emission is contained in a narrow beam. It projects sound outward in a very narrow angle, so anyone who is not near the on-axis angle for the ...
