Why are the functions tan `omegat` and cot `omegat` periodic but not harmonic ?

Explanation

To understand why the functions \( \tan(\omega t) \) and \( \cot(\omega t) \) are periodic but not harmonic, we can break down the explanation into a step-by-step analysis.

### Step-by-Step Solution:

1. **Definition of Periodic Functions**:
- A function is periodic if it repeats its values at regular intervals. For example, the functions \( \sin(\omega t) \) and \( \cos(\omega t) \) have a period of \( 2\pi/\omega \).

2. **Periodicity of \( \tan(\omega t) \) and \( \cot(\omega t) \)**:
