How does a polynomial which isn't a fraction relate to that dx/dy = dx/dt * dt/dy shit

And then he mentions "Respect the X" and shit like that.


ur professor grew up in the bronx or some shit


RESPECT THE X, YO

edit: for related rates


if V(volume) = like, x^3

then the derivative of both sides with respect to T would be (using implicit differentiation)

dV/dt = 3x^2 (dx/dt)

The actual reasoning behind dx/dy=(dx/dt)(dt/dy) is something you probably wouldn't touch until 4th year or possible graduate math studies ; if you're in first year you're just supposed to accept it for now, the proof is a bit beyond calc 2 :p

well....... remember your position graphs. x(t)=x^2, dx/dt= change in x with respect to t = v(t)= 2x. dx/dy^2= change in x with respect to t with respect to t = a(t) = 2

My professor is retarded. I think he was homeless before he got this job from the economy.


He never explained fully the meanings behind dx/dy = du/dx dy/dx

Or whatever that is.

I am paying for education when I can just get it for free at khanacademy.


This might help.

Probably.

There's a video of him on the subways on youtube playing the guitar for money.

In calculus classes, you do a lot of things w/o really knowing the complete reasoning for why you can do it. In Analysis I & II etc you go into detail about all the things you took for granted in Calc I - III
