Mathematics I / Applications of Differentiation
Practice question · Multiple choice

Velocity, acceleration and marginal cost are all derivatives of quite different things. What do the three have in common?

Hints
  1. Write the units of each as "something per something".
  2. The differences are in what is being differentiated.
Show the answer

B. Each is an instantaneous rate of change of one quantity per another

Why

One operation, many readings. Marginal cost is dC/dqdC/dq exactly as velocity is dx/dtdx/dt, which is why an economist and a physicist use the same calculus.
