Question

How do you differentiate `25-pi/3`?

Answer 1

Assuming that `pi` has its usual meaning, The derivative of `f(x) = 25-pi/3` is `0`.

Explanation:

With `pi` equal to the ratio of the circumference of a circle to its diameter, `25-pi/3` is a constant. (It's about `24`.) So its derivative is `0`.
