If `tan(x+y)+tan(x-y)=1` , find `(dy)/(dx)` .

Text Solution

AI Generated Solution

To solve the equation \( \tan(x+y) + \tan(x-y) = 1 \) and find \( \frac{dy}{dx} \), we will differentiate both sides with respect to \( x \). Let's go through the steps one by one. ### Step 1: Differentiate both sides We start with the equation: \[ \tan(x+y) + \tan(x-y) = 1 \] Differentiating both sides with respect to \( x \): ...
