find the general values of '`theta`' from the following equations`tantheta+tan2theta=tan3theta`

Explanation

To solve the equation \( \tan \theta + \tan 2\theta = \tan 3\theta \) and find the general values of \( \theta \), we can follow these steps:

### Step 1: Rewrite the equation in terms of sine and cosine
We start with the equation:
\[ \tan \theta + \tan 2\theta = \tan 3\theta \]
This can be rewritten using the definitions of tangent:
