comment How can I save both the plot and the legend together?
@MikaIke you can drag the cursor over both the legend and the plot. Start slightly to the right of the legend, click down, drag over both until both are selected (they are semi-transparently colored), then release mouse button.

comment Plot3d of explanation of partial partial derivatives
The vertical plane in your figure is not a depiction of a function, as it is multi-valued. Therefore it can't be plotted by Plot3D, which is meant for functions only.

comment Circular Orbit Velocity in Vector Components
V and r should be perpendicular for a circular orbit. With your definition this is only true at 45 degrees because cos and sin are the same there. Doesn't work for other values. You should swap cos and sin in your definition of v. I'd vote to close again if I could as this involves a simple error not related to Mathematica.
