The power of Dark Energy may be increasing as the universe ages. Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent...

One hundred sixty years after the invention of the needle and syringe, we're still using them to deliver vaccines; it's time to evolve. Biomedical engineer Mark Kendall demos the Nanopatch, a one-centimeter-by-one-centimeter square...

New ReviewIn this math video lesson, students learn how to write a system of linear inequalities from a given graph by analyzing key features of each boundary line and the shaded solution region. The modeled example begins by identifying the...

New ReviewIn this video, I will show you how to graph trigonometric functions, specifically focusing on cosecant (csc) and sine. We will examine how to identify key characteristics such as amplitude and period to effectively graph these functions....

New ReviewIn this video, I'll walk you through three essential tips to help you graph sine and cosine functions effectively. We focus on understanding the core components like amplitude and period, which are crucial for accurately plotting these...

Pupil outcome: I can produce an exploded diagram to show different parts. Key learning points: - Exploded diagrams visually separate the parts of an object while maintaining their relative positions. - Effective exploded diagrams include...

Pupil outcome: I can produce cross-sectional drawings to show internal details. Key learning points: - Cross-sectional drawings help see inside objects by cutting them open on paper. - Cross-sectional drawings are used when important...

Pupil outcome: I can use my understanding of various graphical representations to solve problems. Key learning points: - Data can be presented in various formats. - A fuller picture can be obtained when considering more data. - Multiple...

Pupil outcome: I can describe and explain the properties of reflections in a plane mirror, and draw diagrams to show how reflections form. Key learning points: - Reflections are the same size as the object, upright, and the same distance...

Pupil outcome: I can construct a set of points that satisfy a set of conditions. Key learning points: - Constructing a set of points a set distance from a given point produces a circle - A compass should be used for this construction -...

Pupil outcome: I can extend my thinking to a linear inequality with 2 variables and can show this can be solved graphically to find a solution set. Key learning points: - A linear inequality involving two variables can be graphed - A...

Pupil outcome: I can find the area of compound shapes involving circles in different ways. Key learning points: - There are multiple ways to find the area of compound shapes. - The most efficient method may depend on the features of the...

Pupil outcome: I can describe a reflection and perform a given reflection on an object. Key learning points: - The line of reflection can be vertical/horizontal/diagonal. - The line of reflection may go through part of the object. - The...

Pupil outcome: I can use my knowledge of algebraic manipulation to solve problems. Key learning points: - Quadratic equations can model real-life situations. - Solutions would need to be interpreted in context. - The difference of two...

Pupil outcome: I can understand how Earth's polar ice caps are changing. Key learning points: - By analysing how the northern polar ice caps have changed, predictions can be made - By analysing how the southern polar ice caps have...

Learn how to enhance your plot with markers and colors.

In this video, we will cover the creation and management of layers in AutoCAD 2D, which are essential for organizing and controlling the visibility of objects in the drawing. You will learn how to create layers, assign properties such as...

Let's join Sue on a treasure hunt! We have a treasure map ready and we know that the X sign marks the spot where the treasure is at, but how do we know how to describe its location on the map? Learning about what’s called the coordinate...

A plot is a visual representation of the data and is especially valuable to analyze data graphically. You can plot with the plot(x,y) function. In the incubator example, we may want to see how the temperature changes...

👉 Learn about graphing a system of inequalities. A system of inequalities is a set of more than one inequalities which are to be solved simultaneously. To solve a system of inequalities graphically, we graph the individual inequalities...

The video is a lecture presentation on solving quadratic inequalities. The speaker begins by reviewing inequality symbols and explains how they provide a range of values rather than a single answer. The speaker then explains the process...

👉 Learn how to graph linear inequalities written in slope-intercept form. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also...

👉 Learn how to graph a system of inequalities. A system of inequalities is a set of inequalities which are collectively satisfied by a certain range of values for the variables. To graph a system of inequalities, each inequality making...
