I am looking at this derivation of velocity in spherical polar coordinates and I am confused by the definition of r, theta and phi.

I thought phi was the co latitude in the r,θ,∅ system and not the latitude. Of course the two are related through the equation 90 - colatitude.

Would this change the derivation ?
