Question

What is the derivative of `4pi^2`?

Answer 1

Remember that `pi = 3.1415926535 . . .` is a constant, and the derivative of a constant is `0`.

By definition, a derivative is the instantaneous rate of change, but a constant evidently does not change, so it cannot have a nonzero rate of change.

Therefore, `d/(dx)[4pi^2] = color(blue)(0)`.
