Here is my question:

Consider the bending of light by the gravitation of the Sun as described by Newtonian physics. Light of frequency f passes at a distance d from the center of the Sun, which has a mass M. Show that the bending angle of the light is proportional to M/d.

I'm absolutely stumped at the math process and steps in relating it to M/d. I'm sure I need to use Newton's Universal Gravitation equation somewhere, but how to get the end result is baffling to me. Any and all help is greatly appreciated.
