# Geodesics of a Parabolic Cylinder

(Please see the attached file for the complete problem description)

Show that the problem of finding geodesics on a surface g(x,y,z) = 0 joining points (x_1,y_1,z_1) and (x_2,y_2,z_2) can be found by obtaining the minimum of:

(please see the attached file)

Hence find the geodesics for the parabolic cylinder y = x^2.

Please show all of your work.
