## Homework Statement

I have a problem where x = x1 + x2, and I need to relate d/dx to d/dx1 and d/dx2 somehow.

## Homework Equations

## The Attempt at a Solution

I'm guessing there is a simple way to do this that I have just forgotten, I know how to find dx, but how can I find d/dx?

Thanks for the help
