Phi and theta
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). WebWhen you integrate in spherical coordinates, the differential element isn't just $ \mathrm d\theta \,\mathrm d\phi $.No. It's $\sin\theta \,\mathrm d\theta \,\mathrm d\phi$, where $\theta$ is the inclination angle and $\phi$ is the azimuthal angle.. For example, attempting to integrate the unit sphere without the $\sin\theta$ term: $$ \int_0^{2\pi}\int_0^{\pi} …

WebThe phi angle (φ) is the angle from the positive y-axis to the vector’s orthogonal projection onto the yz plane.The angle is positive toward the positive z-axis.The phi angle is between 0 and 360 degrees. The theta … WebThe cut type can be either planar (phi is fixed, theta is swept) or conical (theta is fixed, phi is swept). The figure below illustrates a planar cut (or phi cut) and a conical cut (or theta cut), and the resulting 2D cross section as it would appear on a polar plot. The procedure that follows describes how to define the 2D cross section.
