In this video, students learn about quadrants and how they relate to coordinate planes. The video explains how to determine the quadrant of a point by examining the values of an ordered pair. It also introduces the concept of UPS (Unique...

In this video, we explore the muscles that facilitate hip flexion and the origins, insertions, actions, and innervation of the iliopsoas.

👉 Learn how to evaluate the six trigonometric functions given a point. When given a point, there are many ways to evaluate the trigonometric functions of the point. The methods include: using the unit circle if the point is a point on...

👉 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...

It explains how to add and subtract two complex numbers. It also shows the graphical representation of sum and difference of two complex numbers.

How to understand reflections of polar points
