Question

How do you find the derivative of `2x+ sin x`?

Answer 1

`2+cosx`

Explanation:

The derivative of this function is equal to the sum of the derivatives of each term.

That is, the derivative equals

`d/dx[2x]+d/dx[sinx]`

This boils down to knowing that `d/dx[kx]=k` and that `d/dx[sinx]=cosx`, so the derivative of the expression is

`2+cosx`
