jlmac2001 Question:

Write the vector V=i+2j+3k at the point (x,y,z)=(1,1,0) in terms of the spherical polar coordinate unit vectors r, theta and phi at that point. Do this again at the point (x,y,z)=(1,1,1). Check your answers by checking the norm of both vectors and comparing to the norm in Cartesian coordinates and by making sure that the signs of each component are as you would expect.

How would I answer this in terms of spherical polar coordinate unit vectors r, theta and phi?

What are the transformation rules between the unit vectors in Cartesian and sph. coordinates?
That's all you need to take into account
