I've been trying to work through this in the context of programming a CNC using a recent trilogy of books:

_Make: Geometry: Learn by coding, 3D printing and building_ https://www.goodreads.com/book/show/58059196-make

_Make: Trigonometry: Build your way from triangles to analytic geometry_ https://www.goodreads.com/book/show/123127774-make

_Make: Calculus: Build models to learn, visualize, and explore_ https://www.goodreads.com/book/show/61739368-make

(oddly the Calculus book was published second, so I guess I'll need to re-read it after I finish the trigonometry book)

Hopefully, this will provide me with a sufficient grounding in conic sections that I can solve my next CNC project with a reasonably efficient set of calculations (trying to do it using my rudimentary understanding of triangles from trigonometry had me 4 or 5 triangles deep, barely half-way to the final point I needed, and OpenSCAD badly bogged down performance-wise).

Thanks for that list, I just ordered them! I hadn't heard of that series before

Glad to!

It's quite recent, but seems very good to me, but my math education is about non-existent, so anything would be an improvement.
