### Nyquist Plot Analysis

Consider the following Nyquist plot, which provides details summarized in the table below. **Note:** The magnitude values are in absolute terms, not in decibels (dB).

#### Diagram Description:
The Nyquist plot is a complex plane diagram with the Real part \( \text{Re}(L) \) on the x-axis and the Imaginary part \( \text{Im}(L) \) on the y-axis. The plot includes the following key features:
- A curve passing through the point where the real part is \(-1\).
- A marked point at frequency \(\omega = 1\) with a phase angle of \(-135^\circ\).
- A marked point at frequency \(\omega = 1.5\) with a phase angle of \(-180^\circ\).

#### Table of Values:

| Frequency (\(\omega\)) | Magnitude (\(|L|\)) | Phase Angle (\(\angle L\)) |
|------------------------|---------------------|----------------------------|
| 1                      | 1                   | \(-135^\circ\)             |
| 1.5                    | 0.5                 | \(-180^\circ\)             |

### Calculations:

Using the information provided:

1. **Gain Crossover Frequency:**
   - The gain crossover frequency is \( 1 \) rad/sec.
   - The phase margin is calculated as:
     \[
     180^\circ - 135^\circ = 45^\circ
     \]

2. **Phase Crossover Frequency:**
   - The phase crossover frequency is \( 1.5 \) rad/sec.
   - The gain margin is given by:
     \[
     \text{Gain margin} = 20 \log_{10}(0.5) \, \text{dB}
     \]

This analysis helps evaluate system stability margins, providing insights into the control system's robustness.
