If x and y are connected parametrically by the equations given, without eliminating the parameter, Find `(dy)/(dx)`.
`x=acostheta, y=bcostheta`

Explanation

To find \(\frac{dy}{dx}\) for the parametric equations \(x = a \cos \theta\) and \(y = b \cos \theta\), we will follow these steps:

### Step 1: Differentiate \(y\) with respect to \(\theta\)

Given:
\[ y = b \cos \theta \]
