Iterating the Function and Complex Numbers

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Sal explains that the most significant common factor of any number is the largest number divisible into both monomials and not necessarily the number with the most significant value. He breaks down two numbers into their prime factors as...

Sal discusses the usefulness of the conjugate of the complex number in this video. First, he shows how to add a complex number and its conjugate graphically and algebraically. Then, he shows how to simplify a rational expression with...

In this video, a complex number is defined and graphed on the complex plane. Sal also shows how to add, subtract, and multiply two complex numbers. He shows how to divide two complex numbers but runs out of time and continues in the...

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

One of the strongest tools an algebra learner develops is the ability to quickly and accurately graph almost any given function. Often doing this quickly and accurately requires rigid transformations to a parent function,...

Expand your knowledge on exponential growth! A concept video features the definition of an exponential function. Eight problem videos cover graphing exponential functions, identifying exponential growth and decay, and applying...

Exponents are number 34897 to the power of 0! The short video explains what a power function is. It also demonstrates how to identify the n portion in a standard, fraction, and square root example.

Use prime factorization to find the greatest common factor of three given values. What are the factors that all three given numbers have in common? Identify them, and then multiply together to get the greatest common factor. Just like...

What is the greatest common factor of two terms in an expression? First prime factor each of the terms. Then find the factors that they have in common. Multiply if needed. That is how to find the greatest common factor. Watch the video...
