Find `(dy)/(dx)` in each of the following: `e^(x-y)=log(x/y)`

Text Solution

AI Generated Solution

To find \(\frac{dy}{dx}\) for the equation \(e^{(x-y)} = \log\left(\frac{x}{y}\right)\), we will differentiate both sides with respect to \(x\). Here’s a step-by-step solution: ### Step 1: Differentiate both sides We start with the equation: \[ e^{(x-y)} = \log\left(\frac{x}{y}\right) \] Differentiating the left side using the chain rule: ...
