Solve `4costheta-3sectheta=tantheta`

Explanation

To solve the equation \( 4 \cos \theta - 3 \sec \theta = \tan \theta \), we will follow these steps:

### Step 1: Rewrite the equation in terms of sine and cosine
We know that \( \sec \theta = \frac{1}{\cos \theta} \) and \( \tan \theta = \frac{\sin \theta}{\cos \theta} \). Therefore, we can rewrite the equation as:

\[ 4 \cos \theta - 3 \cdot \frac{1}{\cos \theta} = \frac{\sin \theta}{\cos \theta} \]
