This video provides a formal definition of odd and even functions and an intuitive sense of their differences. Sal examines the graphs of both types of functions to show their reflection properties. Functions that are neither odd nor...

A new SAT practice session (from page 669 of The Official SAT Study Guide) begins with problems 1-5. Sal demonstrates quick thinking and contemplative problem solving as he moves efficiently from one equation to the next.

Transform the review process in the class. Learners review the three types of transformations from the unit: translations, reflections, and rotations. Scholars work on a few quick problems to review the key points of each transformation....

Turn the class around. Scholars define rotations of multiples of 90 degrees and create algebraic mappings for them. After an introduction to symmetry, pupils determine which letters of the alphabet have rotational and reflectional...

Symmetry shows up in equality. Pupils view four examples as the presenter determines whether the equations have symmetry about the x-axis, the y-axis, and the origin. Each equation has at least one type of symmetry. The video works...

You can flip them and the graph looks the same. An instructional video shows how to determine whether an equation contains a graph that has symmetry. Scholars learn how to calculate algebraically whether an equation has symmetry about...

A few more examples can't hurt. An informative video continues the examination of even and odd functions from a prior video. It looks at two additional examples of functions, one that is even and one that is neither even nor odd.

Here's a hint: look at the exponents. Scholars watch a video that shows two examples of how to algebraically prove whether a function is even or odd. They then see how the exponents in a polynomial function relate to the determination.

Our brains may misrepresent features that make some faces look more alike than they actually are. Learners watch a video lesson that breaks down how the brain reads facial features and how those features themselves are not as important...

Find ways to spin a figure without it looking like it was rotating. The segment of a large geometry playlist introduces the idea of rotational symmetry. Using presentation tools, the presenter demonstrates whether particular figures have...

Symmetry is a natural thing. The video introduces the concept of reflection symmetry using a smiley face and a pentagon. Using pictures from nature, the installment of an extensive geometry playlist determines whether the object has...

Ready to tackle the concept of symmetry? Show your class a video that combines it with football, and you'll definitely score the extra point! The resource illustrates different types of symmetry and relates it to both muscle memory...

Eleven problems provide pupils the opportunity to find the lines of symmetry or identify rotational symmetry. Scholars alter designs to make them symmetrical, learn to recognize signs that are symmetrical, and identify the type of...

While our outsides are mostly symmetrical, our internal organs aren't. Why would this be the case? Are other animals the same? What determines if your organs are on the "correct" side or backwards? Here's a video that answers these...

Help learners recognize the characteristics of a quadratic graph and how changes affect them. An informative video uses a graphing calculator in order to find out what happens when the leading coefficient of a quadratic...

Numbers are even and odd, but did you know functions can be too? The lesson shows the process of determining an even or odd function algebraically. It uses polynomial examples and shows an example of each type. 

Sal goes into detail when solving these problems on the practice MTEL math test, especially the complicated details of question 36. Viewers will rest assured of the ease with which Sal addresses these increasingly tricky problems.

Through a video lecture, students discover the visual side of the important applications of mathematics in practical life. More specifically, they will understand the relationship of mathematics and decoration or art.
