Nope, false alarm. Same for the fire.
Any reason to think you have to get exact solutions to the equation?
Also, have you tried drawing the curves .... you realise that is a line ...?
We have somewhat tired converting the equations to cartesian equations with conversion formulas, but it turned out..funny.
If you can do it, that would be wonderful.
We also know you can graph them as cartesian equations and get the intersections, but if we were to do that (according to our teacher) we have to have proof of why it works.
Thank you for your input, We'll look forward to more help.(Talking)
Yeah, we need exact..our teacher is a tad insane.
Good..but very insane.
Yes we know it's a line, but how is that going to help us solve the situation?
From (2), .... (3).
Substitute (2) and (3) into (1) and re-arrange into a quartic equation in r. You might get r from this (I'll cop that I haven't actually tried .....)
I'm a little confused as to how you got that last line, but I'll work on it and get back to you.
