I just ran into an interesting problem with this. the students
messed up two problems because their calc. course reversed the
definitions of theta and phi in spherical coordinates (I always thought
physics, and everyone else had theta from the z-axis, and phi as the
azimuthal angle). They even showed me their calc. text with the angles
reversed. Sheesh...things you wouldn't even expect when teaching :)
