Differentiate the following :
(i) `(theta)/(tan theta)`

Explanation

To differentiate the function \( y = \frac{\theta}{\tan \theta} \), we will use the quotient rule. The quotient rule states that if you have a function in the form \( \frac{u}{v} \), then its derivative is given by:

\[ \frac{dy}{d\theta} = \frac{v \frac{du}{d\theta} - u \frac{dv}{d\theta}}{v^2} \]

where \( u = \theta \) and \( v = \tan \theta \).
