WebFeb 10, 2024 · Euler angles are specified by the three angles, viz., $\psi$, $\theta$, $\phi$. Euler angles represent three consecutive rotations in the order of $\psi$, $\theta$, $\phi$ so that one coordinate axes system is made to coincide with another system. Again, the order of rotation, i.e., $\psi$, $\theta$, $\phi$, is very very important. WebN69sZelda • 10 yr. ago. I think he is referring to how spherical coordinates are switched between math and physics. In math r is the radius, phi is the polar angle, and theta is used as the azimutal for the angle from the "x" axis in the x,y plane. Physics switches this so that theta is the polar angle (from the z axis).
