What always puzzles me ( and maybe I am wrong ) is, that the xyz coordinates are kind of self sufficient, but the spherical coordinaten seem to be embedded in the cartesians. They need the xy plain as a reference for theta or the z axis as reference for phi. ?
That's covered by some values of theta. That is, there are some values of theta that would produce the same the effect. So, see, that for the same phi, you can use theta = pi/2 and theta = 3pi/2 to produce two different values. One of which would be 'phi' = 3/2 pi. Just like (x, y, z) are unique, you want (rho, theta, phi) to be unique as well.
Really enjoyed the way you explain the concepts. Your Cal 3 content come in handy during this epidemic. Thank you!
Good explanation,keep on posting vedios,we love it
Finally I found good explanation, thank you so much

Why can’t phi take the value of, say 3/2 pi?
