Have you made any attempts on this so far?  Or just lost?

anonymous · Answer

I'm lost. O: I'm confused on how to form the equation

accessdenied · Answer

Hm... I have two ideas.
One way seems like it would take quite a bit of work, would just be converting to rectangular coordinates and then using distance formula.  That sounds ew to me because of a lot of steps

The other is, for the most part, using Law of Cosines.
Either of these seem good to you?  :)

OpenStudy... ;~;
I am assuming by "form the equation" we are heading towards the Law of Cosines route
$ c^2 = a^2 + b^2 - 2ab \ \cos C $

The way it works is by drawing the two points, their segments with the origin and between each other, you create a triangle.  The most catching part might just be the angle.  But if you sketched this situation out, you might get a hint at the set-up.
