Tutorial - Graphing complex numbers ex 2, 1 - 4i

The video tutorial explains how to graph complex numbers on a complex plane. It begins with an introduction to the complex plane, detailing the real and imaginary axes. The instructor then describes the form of complex numbers as a+bi, where 'a' is the real part and 'bi' is the imaginary part. The tutorial proceeds to demonstrate how to plot a complex number by using the distances on the real and imaginary axes, specifically plotting the complex number 1-4i. The video concludes by summarizing the process of combining the real and imaginary components to identify the complex number point.

What are the two axes called in the complex plane?

• Real and Imaginary

• X and Y

• Positive and Negative

• Horizontal and Vertical

In the form a + bi, what does 'a' represent?

• Angle

• Imaginary part

• Real part

• Magnitude

How do you determine the position of a complex number on the complex plane?

• By using the magnitude and angle

• By using the real and imaginary components

• By using the x and y coordinates

• By using the positive and negative values

What is the real component of the complex number 1 - 4i?

• 1

• -4

• 0

• 4

Where is the point for the complex number 1 - 4i located on the complex plane?

• Over 1 on the real axis and up 4 on the imaginary axis

• Over 1 on the real axis and down 4 on the imaginary axis

• Over -1 on the real axis and down 4 on the imaginary axis

• Over 4 on the real axis and down 1 on the imaginary axis
