Hello all you hot & helpful math masters. Please help me with this:

I'm doing correspondence course, grade 11 math(Canada) - course is just called Functions & Relations. My final Unit is called, "Investigations of Loci & Conics."

The lessons will cover the following: Trig Equations & Identities, Investigating Loci & Circles, Ellipses, Parabolas, Hyperbolas.

My problem is when I am searching help forums or online resources, I never know if I should go to the Calc, Pre-calc, Trig, Geometry sections for fast finding of info I need.

Any suggestions or help categorizing would be greatly appreciated!
