Suppose the x coordinate of a pie is given as a function of time t by

x(t) = (u^2)(t^2) + 3ut,

where u is independent of t. Calculate (dx/dt) and (dx/du). Also, whihc one of the above derivatives (if either) give you vx, the x component of the pie's velocity?

2. Relevant equations

Just derivative rules.

3. The attempt at a solution

(dx/dt)= 2(u^2)t + 3u

(dx/du)=2u(t^2) + 3t

Since t represents tiem in this function, to obtain the velocity you must use (dx/dt).

Please let me know if this is correct or if I am missing a step.
