/sci/ - Science & Math

I was watching Meme Academy, and I witnessed Sal derive a kinematic formula, [math]\vec{s}=\vec{v_o} \Delta t+\frac{1}{2}\vec{a}\Delta t^2[/math] . I mean, it's all cool and shit, pretty simple, easy, but how the fuck could I ever derive this on my own, without even knowing what to use as a substitution instead of something in the equation?

Is this one of those formulas, that you just learn to derive by heart, just because x is something that must absolutely be substituted by (y+z), even though it could be also substituted by 2(p+q), but if we did that, it wouldn't work?

Like, how the fuck do I learn what to substitute for what to derive my formulas? There must be a logical solution to this, right?

It's wishful thinking I that I am 1 in a 100 000 people super smart. I consider myself average. I struggle with even calculus derivative concepts. But I spend my time here because this is like a science news article board, as soon as there is something new, /sci/ is the first to find and post it here.
