# How do you find the derivatives of y=ln(x+y)?
##### 1 Answer
May 29, 2017
$\frac{\mathrm{dy}}{\mathrm{dx}} = \frac{1}{x + y - 1}$
#### Explanation:
Here's another method.
$y = \ln \left(x + y\right)$
${e}^{y} = {e}^{\ln} \left(x + y\right)$
${e}^{y} = x + y$
The derivative of ${e}^{a}$ is ${e}^{a}$. Therefore... | HuggingFaceTB/finemath | |
# How to write an equation in slope intercept form?
