In this video we are going to go over how to determine the other quadrants of the unit circle

When you are learning about the Unit Circle the most important part is the first quadrant. In this video I will explore how the first quadrant is created and where the values come from.

In this video we are going to explore an easy problem for evaluating the inverse of the tangent function and a hard problem for evaluating the inverse tangent.

A video entitled "Comparing Domains of Functions" that covers the process of determining whether the domain of a function representing a real-world scenario should be restricted.

In this video, the speaker explains the structure of a sonnet, a poetic form consisting of 14 lines written in iambic pentameter.

This video, entitled "Reflecting Angles," shows how angles can be reflected over a line of reflection.

Howcast - Check out part 15 of our walkthrough for Crysis 3, the new first person shooter title by Crytek, and learn how to harness the nanusuit to beat the Gods and Monsters mission.

Pupil outcome: I can explain how negative numbers are used on a coordinate grid. Key learning points: - Coordinates can include negative values - The x or horizontal value is always the first value in a coordinate - The y or vertical...

Pupil outcome: I can draw and complete simple shapes by plotting positions on the full coordinate grid. Key learning points: - The horizontal distance or coordinate is given first when describing positions on a coordinate grid. - If the...

Pupil outcome: I can reflect simple shapes in the axes on a full coordinate grid. Key learning points: - When reflecting a shape in the axes, the reflection and original shape should be the same distance from the axis. - The shape...

Pupil outcome: I can plot coordinates in the first quadrant. Key learning points: - Coordinates can be plotted in the first quadrant. - Shapes can be described using coordinates. - Moving all the points of a shape using the same rule...

Pupil outcome: I can plot coordinates in any quadrant. Key learning points: - Coordinates can be plotted in quadrants two and four. - Coordinates can be plotted in the third quadrant. - Shapes can plotted in one quadrant. - Shapes can be...

Pupil outcome: I can plot coordinates in any of the four quadrants. Key learning points: - It is possible to plot coordinates approximately in the correct quadrant. - Coordinates can be plotted exactly when the axes are labelled. - By...

This is my second video on deriving the Unit Circle. If you know where the angles (degrees and radians) come from, your next step is to use special right triangles to derive the points on the Unit Circle.

In this video, we learn the 1-2-3 method for memorizing the points on the unit circle. This is not a video where we derive the unit circle, I have other videos about that. Here, we just try to memorize the unit circle so that we can...

In this video, we define reference angles, learn formulas for reference angles, and learn how to calculate reference angles. Personally, I focus more on visualizing the angle itself vs memorizing the formula

How do you solve trig equations with the values are not on the unit circle? When your solving results in decimals, you can the inverse trig function in the calculator to find the solution. Then, use reference angles to find he other...

In this math video we will be plotting points on a graph. We will learn that an ordered pair is written in the form (x, y) where x tells us the horizontal distance to travel right from the origin followed by a vertical distance of y. We...

This video explains how the technique of flow cytometry is used to detect for the presence of apoptotic cells in a given cell population. The technique used is Annexin V-Propidium iodide staining. Annexin V is a calcium-dependent...

What is the Johari Window? The Johari window is a technique designed to help people better understand their relationship with themselves and others. It was created by psychologists Joseph Luft and Harrington Ingham in 1955, and is used...

Valence electrons are the electrons in the outermost energy level of an atom. They are important because they are involved in the chemical bonding of our elements which helps determine the reactivity of elements. In order to be stable,...

Find out how labyrinths and mazes are created, and how to navigate your way through each. Maths - Shape A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s math films show abstract concepts in action in...

A team can focus on two things: task and relationship. And, for each, there are 2 elements: the content and the process. This gives us 4 quadrants of team leadership.

In this video we will explore how to evaluate the six trigonometric functions when given an angle
