Find `(dy)/(dx)ifx=a(theta-sintheta)a n dy=a(1-costheta)dot`

Explanation

To find \(\frac{dy}{dx}\) given \(x = a(\theta - \sin \theta)\) and \(y = a(1 - \cos \theta)\), we will follow these steps:

### Step 1: Differentiate \(x\) with respect to \(\theta\)
We start by differentiating \(x\):
\[ \frac{dx}{d\theta} = a\left(\frac{d}{d\theta}(\theta) - \frac{d}{d\theta}(\sin \theta)\right) \]
\[
