To find the argument of a complex number, here are some easy steps to follow:

1. Change to Polar Form: First, rewrite the complex number as $z = r(\cos \theta + i\sin \theta)$. This form helps us see the angle more clearly.

2. Use Tangent: You can use the formula $\tan(\theta) = \frac{y}{x}$. In this formula, $y$ stands for the imaginary part, and $x$ is the real part of the complex number.

3. Look at the Quadrant: Make sure to check if $x$ and $y$ are positive or negative. This tells you which quadrant the angle $\theta$ is in.

These tips really helped me understand the concept better!
