n this video, I explain the abdominal reflex. More specifically, we discuss the reflex arc and how to determine whether or not the reflex is present/normal or abnormal.

Here's some vocabulary that we usually learn as children in our native language(s), but that we often don't learn in foreign languages... I hope you enjoy this little lesson on English vocabulary for board games.

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

👉 Learn how to evaluate the six trigonometric functions of a given angle. When given an angle we locate the angle on the unit circle. Then using the coordinate of the terminal side of the angle on the unit circle and the definitions of...

To find the moment of a force about a point simply multiply the force by the perpendicular distance from the force vector to the point.

👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

This video explores how our eyes and brain interpret images and showcases various optical illusions. It demonstrates how focusing on one thing can make another disappear and how our brain can be tricked into perceiving images...

In this video lesson we will learn how to rotate figures in the coordinate plane about the origin. We will understand that all rotations result an image that is congruent to the original figure. The origin will be the center of...

Learning how to assign absolute configuration (R/S) to any stereocenter.

The video provides a basic introduction to angle facts, including how to measure and classify angles. The speaker explains the different types of angles, such as acute, obtuse, right, reflex, and full turn, and provides examples of how...

👉 Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies...

In this lesson on rotations, students will learn how to identify rotations and rotate figures in the coordinate plane. They will understand the vocabulary of transformations and how to tell when a transformation is a rotation. The...
