His brain is clearly being used to try to write backwards haha

Hi, My name is Stefan, and I have no idea what I'm doing :)

[karensolomon]

am I the only one who clicked on this video because they don't know how to derive an equation and he looks like he just made a fairly simple equation a million times more complicated? maybe thats how its supposed to be. idk.

It's like he said : "heck yeah, i can teach physics stoned !!"

[gerdbc]

he broke into the room, put the shirt on and started rolling the camera. he managed to upload this before the police came

Why in the world does this guy look so confused?

Okay here is what he is trying to say.... My name is Stefan, and today I'm going to teach you how to derive a Physics equation, to make it easier for you so that you'll be able to understand, we will derive this equation v(t) = at + v(0), so let's derive this equation: Well here we are trying to derive an equation for velocity, so well start by saying what we know about velocity, 1) We know that velocity is the rate of change of position which is given by v(t) = dx/dt. 2) We also know that velocity is the area under an acceleration vs time graph, and so it is given by v(t) = S[a]dt (S = Integral Sign), intergating this integral we get S[a]dt = at + C, C is a constant which we need to find, and by looking at our equation which we just found v(t) = S[a]dt = at + C, we can see that at time t = 0, we get v(0) = a(0) + C, which is v(0) = C, and therefore we see that our constant C = v(0) in other words, our constant is equal to the velocity at t = 0. Therefore the equation turns out to be v(t) = at + v(0).

lol!!! what is this?! bewildered by such a simple derivation????

[oscarbraso]

But its basic math so i quess im still no good...

[lordth]

He is just thinking about the formulas and nothing comes into his mind except his doesn't have any idea how V = u + at😂😂😂... He is sooo His brain cells

Why do you look like youre not sure on what your teaching? HAHA, then look at your fingers, they are pinkish dirty, lookslike you have to erase the board coz I think you have done this for many times, and fail to do so. HAHA btw cngrats dude.
