Key Concepts

Complex Numbers

Complex numbers are numbers that have a real part and an imaginary part, expressed in the form a + bi. They extend the idea of the one-dimensional number line to a two-dimensional complex plane, allowing for a broader range of mathematical operations and applications.

Complex Plane

The complex plane, also known as the Argand diagram, is a two-dimensional plane where complex numbers are graphed. The horizontal axis represents the real part of the complex number, while the vertical axis represents the imaginary part, providing a visual understanding of their magnitude and direction.

Polar Form

The polar form of a complex number expresses it in terms of its magnitude and angle instead of its Cartesian coordinates. It is typically written as r(cos? + i sin?) or r·e^(i?), where r is the distance from the origin (modulus) and ? is the angle (argument) measured from the positive real axis.

Modulus

The modulus of a complex number is the distance from the origin to the point representing the complex number in the complex plane. It is calculated using the formula r = ?(a² + b²), where a and b are the real and imaginary parts respectively.

Argument

The argument of a complex number is the angle that the line connecting the origin to the point makes with the positive real axis. This angle, often denoted by ?, is essential in converting the complex number to its polar form and can be expressed in degrees or radians, depending on the context.

In Problems 13-24, plot each complex number in the complex plane and write it in polar form. Express the argument in degrees. $-3 i$
