Hi everyone,

Im currently following an example of this paper:

http://ocw.mit.edu/courses/aeronauti...7F09_Lec18.pdf
And have reached a standstill on page 5. Im trying to plot the pseudo potential of the two bodies. I have succeded in plotting the gravitational potential in maple. But when i want to plot the pseudo potential i have to use the function (14). But on the added centrifugal force theres r, which i pressume is the position vector.

Im not really sure how to plot this since i now have 3 (x,y,r) variables instead of 2(x,y). r must be some sort of function of x and y, i think? If anyone has ever plottet the potential field i would love to know what to do now.

Regards

and thanks in advance.
