Why learn it in school when this guy can explain it to you for free with a whole lot more clarity -even though my sound isn't working on this computer. I would pay to have this dude teach me Multivariable Calculus... Or is this Differential Equations?
1. A trajectory (or any kind of motion in space that adheres to mathematic description)of a particle is written in terms of parametric equations x=f(t),y=g(t)
2.Speed it the magnitude of the velocity vector ( a number with no direction) and is found by the change of arc length per change of t (ds/dt) iow(in other words) the derivative of the arc length function wrt(in respect for) t.
Oh and another note you can also find speed in the good old fashioned way of taking the magnitude by using the pytagorian theorem on it's components like dony shows in the video (Yeah I wrote the notes too early..)
You're kinda cute haha. I think I would be distracted if I had you as a teacher. /creeper

You should do single-variable calc. videos for all us newbs out there.
