    Did you happen to determine your Wronski after that ?

      Jesus christ. Dot products are high school math.

        This makes me extremely sad.

          Dude, dot products are something you learn in Geometry. And again in Algebra II. Did your ****ty philadelphia high school not teach those math classes?

              How about failure because he needed either one?

                  I'm amazed Alby has no idea what a dot product is.

                    I don't remember that, honestly, and I remember enough from geometry to regularly help eighth-grade geometry students. Looked it up on Wiki, but couldn't be bothered to decode the mathspeak enough to figure out WTF it was talking about. Maybe if I were a big math person who used it, I would remember it?

                        You probably know it at some level in terms of the trigonometry then, but don't know it by that name. If I have vectors A = <1, 2> and B = <3, 4> then dot(A, B) = 1*3+2*4=11. It's also equal to the magnitude of A times the magnitude of B times the cosine of the angle between them--|A||B|Cos(theta).

                          Actually I don't remember that from my math days and I was on the advanced math track back then.
                          But then I have a wrist band with my address on it so take it for what it's worth.

                            Yeah, don't remember learning that at all. Of course, everything after Algebra II is a bit of a blur. I know we didn't spend all of Trig learning about cosines and such, but that's all I can remember of it. That, and this thing where we drew an oval using a string attached to two pegs in a board. Pre-cal, I remember nothing but derivatives. Calc, I remember an amusing anecdote of the teacher's about a cow getting drunk on fermented watermelon. Also a far less amusing Hamlet reference (2x OR NOT 2x HAHAHA) that he pulled out at every damn opportunity. The actual subject I remember as utterly incomprehensible. Probably some combination of his teaching and my senioritis. I didn't even want to take the stupid course, I'd have rather left it at Pre-Cal, but I had to take a math every year. Grr.

                            So, yeah. That's new to me.

                              I should add that what's taught in which math class apparently varies widely. In my day, for example, you took Algebra II, then Trig, then Pre-Cal, then Calc. Really quick students took a condensed Algebra II plus Trig class. But in the schools I sub, Pre-Cal is just another way of saying "advanced trig with a week of very basic calculus stuff thrown in at the end." So, it's just Honors Trig. They have this funky high school science sequence, too, where the lower kids take ocean science instead of bio. So you can't assume everybody learns the same thing at the same time.

                                No one knows your esoteric math, HC and regexcellent.

                                The rest of us haven't had a math class in a decade or more and have never had to use anything beyond basic algebra and statistics.

                                Yuk it up but you're in the tiny minority.
