Quick question about derivatives involving Newton's dot notation and the chain rule:
I was just wondering if, say you have a velocity function in terms of t, would that be considered xdot?
So for example, if they give x=2t and that's in terms of velocity, it's xdot? And then the derivative of that for acceleration would be xdouble dot?
Furthermore, say you have a velocity position function y=x^2. Would the chain rule for that be y = 2x*(xdot)?
If you're confused by when I say xdot, I'm talking about this:
