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.
