I dove into some online courses from MIT and my basic math skills are a little rusty. In the basics physics course the instructor writes an example on the board:
x = 8 -6t + 2t²
Simple enough, next he says to pull the velocity out of that formula he does:
"All I'm using is"
x = t^n
"Which as all you all know is"
dx/dt = nt^(n-1)
v = -6 + 2t
I'm having trouble following this a little bit. I understand why the velocity is what it is, but taking x = t^n and applying it to x = 8 -6t + 2t² is where I'm missing something.
I looked up some laws on derivatives but still can't piece this together. Thanks for the help guys.
