Find `(dy)/(dx)` in the following:`a x+b y^2=cosy`

Explanation

To find \(\frac{dy}{dx}\) for the equation \(ax + by^2 = \cos y\), we will differentiate both sides with respect to \(x\).

### Step-by-Step Solution:

1. **Differentiate both sides with respect to \(x\)**:
\[ \frac{d}{dx}(ax + by^2) = \frac{d}{dx}(\cos y) \]
