# Math Help - Differentiating implicitly

1. ## Differentiating implicitly

Hi all,

I am revising on how to differentiate implicitly. I know how to find dy/dx for:

x+y

when it is equal to something. The problem here it is not equal to anything and I have both 1+dy/dx stuck on one side. What am I supposed to do here?

when x+y what is dy/dx?

I am getting 1+dy/dx but on one side.

Thanks.

All right, if $f(x)=x+y(x)$ then, $\dfrac{d}{dx}f(x)=1+\dfrac{d}{dx}y(x)$
