Key Concepts

Polar Form Representation

The polar form of a complex number expresses it as r (cos ? + i sin ?), where r represents the modulus or distance from the origin, and ? represents the argument or angle measured from the positive real axis. This form is especially useful for multiplication and division of complex numbers.

Modulus and Argument Calculation

To convert from rectangular to polar form, the modulus r is calculated using the formula r = ?(a² + b²), and the argument ? is determined using inverse trigonometric functions, typically arctan(b/a), ensuring the angle is adjusted based on the correct quadrant. When expressing the argument in degrees, the computed angle in radians is converted by multiplying by 180/?.

Complex Numbers

A complex number is expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit. This form highlights the real and imaginary components and is fundamental for understanding both algebraic operations and geometric interpretations.

Plotting in the Complex Plane

Plotting a complex number involves representing it as a point in a two-dimensional plane, where the horizontal axis corresponds to the real part and the vertical axis corresponds to the imaginary part. This visual representation aids in understanding complex number operations and relationships.

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