Hey there. This recent unit we did was conics. It was all about cones and stuff. I found this to be pretty simple, just like the stuff we did in grade 11 pre cal with parabolas.
there is a little diagram of how the shapes were formed.

Circle formula:\left(x - a \right)^2 + \left( y - b \right)^2=r^2.
Elipse formula:\frac{x^2}{a^2}+\frac{y^2}{b^2}=1
Parabola formula:(x-h)^{2}=4p(y-k)\, or horizontal parabola:(y-k)^{2}=4p(x-h)\,
Hyperbola formula:\frac{x^{2}}{a^{2}} - \frac{y^{2}}{b^{2}} = 1

I hope everyone gets an A+! don't forget about DEV projects
