Question

What is the derivative of `((pi x) / 3)`?

Answer 1

`pi/3`

Explanation:

We will use the rule: `d/dx(cx)=cd/dx(x)=c`

In other words, the derivative of `5x` is `5`, the derivative of `-99x` is `-99`, and the derivative of `5/7x` is `5/7`.

The given function `(pix)/3` is the same: it's the constant `pi/3` multiplied by the variable `x`.

Thus, `d/dx((pix)/3)=pi/3d/dx(x)=pi/3`.
