In this video, the teacher explains how to find the shortest distance between two points on a coordinate plane using the Pythagorean theorem. They demonstrate the process by creating right triangles and plugging the values into the...

It provides solved problems based on co-linearity of points, proving the coordinates to be the vertices of a geometrical figure and on finding locus.

Learn how to write the equation of a parabola given the focus and the directrix. A parabola is the shape of the graph of a quadratic equation. A parabola can open up or down (if x is squared) or open left or right (if y is squared)....

Learn all about parabolas in conic sections. We will discover the basic definitions such as the vertex, focus, directrix, and axis of symmetry. We will also take a look a basic processes such as graphing, writing the equation and...

Learn how to graph horizontal ellipse not centered at the origin. A horizontal ellipse is an ellipse which major axis is horizontal. To graph a horizontal ellipse, we first identify some of the properties of the ellipse including the...

Learn how to write the equation of an ellipse from its properties. The equation of an ellipse comprises of three major properties of the ellipse: the major radius (a), the minor radius (b) and the center (h, k). The ellipse is vertical...

A ball flying through the air, a deer walking in the woods, and a flowing river - these are all examples of moving things. This action-packed video explores the characteristics of things in motion. Special attention is given to the...

Astronomers have seen light from BEHIND a black hole for the first time. I explained the discovery and results to my editor, Levi. Congrats to D. Wilkins and the astronomy team!

A large asteroid classified as “potentially hazardous” by NASA will zoom past Earth on March 21, according to NASA's Center for Near-Earth Object Studies

Willamette Valley's specialty seed crops face threats from cross-pollination due to its unique geological and weather conditions that are ideal for seed production. A detailed mapping system and distance standards for crop isolation are...

This is the second part of a two-part video that shows how to assess and manage risks. This clip is from the chapter "Certified Information Systems Security Professional CISSP Domain 1 - Security and Risk Management" of the series...

Today, we are going to walk through an example problem. Remember, for each truss we follow the same steps: 1. Calculate the missing angles (if necessary) 2. Calculate static determinance (2J=M+R) 3. Calculate reaction forces 4. Calculate...

Learn how to graph vertical ellipse centered at the origin. A vertical ellipse is an ellipse which major axis is vertical. To graph a vertical ellipse, we first identify some of the properties of the ellipse including the major radius...

Learn how to graph a parabola in when it is given in general form. To graph a parabola in conic sections we will need to convert the equation from general form to standard form by completing the square. Once it is in standard form we can...

How to graph a polar point with a negative radius

👉 Learn how to determine the figure given four points. A quadrilateral is a polygon with four sides. Some of the types of quadrilaterals are: parallelogram, square, rectangle, rhombus, kite, trapezoid, etc. Each of the types of...

Ever wonder why the force due to gravity doesn't show up on the final equation of motion? It's NOT because we neglect the mass of the block, it's because of the static deflection term.

Today we're going to look at voice leading. Voice leading is a way to get from chord to chord in music that makes it sound connected (and can make it easier for musicians to play). First, we will take a chord progression, add a bass line...

In this video, the teacher explains how to interpret input and output values in the context of functions. Using real-world examples like distance traveled and circumference of a circle, the teacher demonstrates how to determine the...

👉 Learn how to determine the figure given four points. A quadrilateral is a polygon with four sides. Some of the types of quadrilaterals are: parallelogram, square, rectangle, rhombus, kite, trapezoid, etc. Each of the types of...

👉 Learn about the points on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

In this series of programs students are introduced to perimeter and area. Easy-to-understand examples enable students to understand the process by which perimeter is calculated. The area of rectangles, parallelograms, and triangles is...
