Let's take one more closer look at learning by spelling words about school. A Day at School, Part 7

Excellent for every American Sign Language (ASL) student as well as teachers, parents and professionals learning ASL to be able to communicate clearly, naturally and start signing with the deaf community and people with hearing loss....

A simple animated video about Neurofibromatosis Type 1 (NF1), a genetic condition that causes lumps to grow on the nerves. We explain why it occurs, the main signs, the complications to be aware of, and how it is managed. This video will...

It's gone by many names, (the pound sign, the number sign, the octothorpe and the hashtag symbol) and it's had many meanings, but what is the origin of this # mysterious symbol? Well the truth is it goes back all the way to ancient Rome....

In this episode of What the Theory, an introduction to semiotics, in particular the approaches of linguists and semioticians Ferdinand de Saussure and Charles Sanders Peirce. Signs, semiotics as well as the concepts of the signifier and...

In this lesson, your instructor David, examines integers; signed and unsigned, how large or small they can be, and what happens if they exceed these limits.

👉 Learn how to find the area of a triangle. The area of a triangle is the measure of the region enclosed by the triangle. There are several methods that can be used to find the area of a triangle depending on the available information....

👉 Learn how to use the double angle identities to solve trigonometric equations. When we have equations with a double angle we will apply the identities to create an equation that can help solve by inverse operations or factoring. We...

👉 Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric equations, they include factoring out the GCF and simplifying the factored equation. Another method is to use a...

👉 Learn how to write a given sum or difference of two angles formula expression as a single sum/difference of angles trigonometric function. To do this, we first identify the trigonometric function for which its sum/difference formula is...

How to understand reflections of polar points

Instructions and demonstration on how to make a 3D Sign using chipboard (thin cardboard). This art lesson was inspired by Shelley Speidell and is used to instruct students in my 8th grade 3D Design course.

Part 2, Painting and...

A description of what variables are, how they are used, and a useful analogy to understanding them.

Excellent for every American Sign Language (ASL) student as well as teachers, parents and professionals learning ASL to be able to communicate clearly, naturally and start signing with the deaf community and people with hearing loss....

👉 Learn how to evaluate the secant of the sum or difference of two angles using the sum/difference formulas. To do this, we first use the Pythagoras theorem to obtain all the sides of the right triangle in the unit circle. Recall that...

👉 Learn how to solve equations using the angles sum and difference identities. Using the angles sum and difference identities, we are able to expand the trigonometric expressions, thereby obtaining the values of the non-variable terms....

Authentication can be configured and managed within a single organization to control access to IT resources. This episode covers identity federation and its relationship to identity and resource providers.

👉 Learn how to evaluate the limit of a function involving trigonometric expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time....

Excellent for every American Sign Language (ASL) student as well as teachers, parents and professionals learning ASL to be able to communicate clearly, naturally and start signing with the deaf community and people with hearing loss....

This video goes over 2 examples, covering the proper way to find integrals that require the repeated application of the integration by parts formula. In addition, the tabular method for integration by parts is also introduced.

There are a variety of ways in which user authentication can be implemented prior to allowing user access to the Internet. This question presents a scenario require user sign-off to a term of agreement before gaining Internet...

👉 Learn how to write a given sum or difference of two angles formula expression as a single sum/difference of angles trigonometric function. To do this, we first identify the trigonometric function for which its sum/difference formula is...

You place a book on a 14° incline and then let go of the book. If the book takes 2.05 seconds to travel 0.78 meters, what is the coefficient of kinetic friction between the book and the incline?

In this video, students will learn how to graph sinusoidal functions by plotting points and observing the terminal ray of the unit circle. They will understand the patterns and periodicity of the sine and cosine functions, and how to...
