Sal solves several problems involving exponential growth functions for two reasons. First, he aims to familiarize viewers with the process, particularly for those who find exponents challenging or daunting. Second, Sal wants to show how...

Put your math pupils’ division and algebra skills to the test with this video, which introduces the concept of polynomial division. Sal's examples increase in complexity as the video progresses, allowing viewers to see how basic skills...

Introduce zeros of a function and their relationship to the graph of the function. an informative video uses the definition of a zero to help identify them on a graph and provides several examples of finding the zeros of a...

Find deeper meaning in graphs. Pupils use the knowledge gained from the previous sections in the unit to sketch graphs of a function's derivative. Learners also see how to sketch a graph of a function given the graph of its derivatives....

At some point the rate of change must be the average. Pupils first see the definition of the Mean Value Theorem and hear an explanation of it in simple terms. The helpful video then compares the Mean Value Theorem with the Intermediate...

Find the zeros on a given graph of a quadratic equation. What does this mean? It means to find the values at which the parabola crosses the x-axis. It seems pretty straightforward to be able to look at a graph and identify the points at...

Starting with a set of values for the x and y variables, this video shows how to tell whether these points determine a linear or non-linear function. Sal first defines linear functions in terms of the change in y over the change in x,...

"Just to get the point drilled into your head," Sal continues his lecture on factoring quadratic expressions, focusing on special products. He works to instill the problem-solving skills necessary to factor in equations quickly and...

Armed with their newfound (or refreshed) knowledge of the quadratic formula, viewers can now work with Sal to prove the formula - an essential skill that is often ignored in algebra. Once they learn how to both use and prove the...

Sal finishes problem 10 in this video, as well as problems 11-13 on page 735. Students can practice skills such as linear functions, slopes, and calculating permutations. Problem 12 allows viewers to see the process of elimination in...

Starting a new set of SAT practice problems from The Official SAT Study Guide (page 518), Sal takes students through some straightforward questions involving basic algebra and functions. However, as every math teacher and student knows,...

A potentially scary equation ends this practice session. However, it is no match for Sal's mathematical prowess. And once they watch him make the complicated methodology simple, your students will feel more confident in their own...

Sal's lecture starts where his last one ended - on problem 13 from The Official SAT Study Guide. Starting the problem over to ease understanding, he explains how to find the pattern in a complicated sequence. The following problem...

Here is a special form of a sum of cubes problem, where students use algebraic multiplication to rewrite each term in expanded form. Sal gives an example before solving the problem to show the process that he will use to determine the...

Sal factors and finds the difference between the two cubed terms because this comprehensive presentation would be perfect as homework support or as an independent workstation.

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to more complex word problems.

Work smarter, not harder! Learn a function of the calculator that assists with creating a table of values. The calculator does the work of substituting values and finding the input-output pairs.

Add up area to find total change. Pupils learn what it means to find the area under a curve and how to calculate it geometrically. They first find the accumulation of change given a rate of change function. Scholars then apply that...

This video introduces the institution and function of banks in society by walking viewers through the concept of banking with colorful annotations and simplified narration. The lecture evolves naturally into a discussion about interest...

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered...

Converting between logarithmic form and exponential form is an important skill in solving problems involving exponents. This video shows how to convert an equation in logarithmic form to exponential form. The instructor reviews the...

Sal demonstrates how to solve an absolute value equation, keeping in mind there are two possible answers.

No one was actually there to see the birth of the universe, but years of collaboration between physicists and mathematicians allow us to glimpse all but a fraction of a second of it. A narrated journey shows the phase changes...

Slope intercept form is one of the three forms we can use to express a straight line. It is a linear function too; meaning the function can tell you its domain and range. Watch this video tutorial for a full explanation along with...
