Practice question · Multiple choice
Velocity, acceleration and marginal cost are all derivatives of quite different things. What do the three have in common?
Hints
- Write the units of each as "something per something".
- 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 exactly as velocity is , which is why an economist and a physicist use the same calculus.
