Welcome ladies and gentlemen. So what I'd like to do is show you how to determine the focus, vertices, as well as co-vertices of an ellipse when the center is at the origin. And again, we know that the center...

👉 Learn how to solve word problems with triangles. A word problem is a real-life situation which can be modelled mathematically. Word problems involving angles of elevation and depression, straight object leaning against a vertical...

You can't understand climate change in pieces, says climate scientist Gavin Schmidt. It's the whole, or it's nothing. In this illuminating talk, he explains how he studies the big picture of climate change with mesmerizing models that...

Learn how to graph horizontal ellipse 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 major...

In this lesson, students will learn about the associative property of multiplication by using the volume formula. They will understand that the order in which they multiply the dimensions of a rectangular prism does not affect the final...

👉 Learn how to solve the word problems with trigonometry. Word problems involving angles, including but not limited to: bearings, angle of elevations and depressions, triangles problems etc are solved using trigonometry. To be able to...

In this lesson, students learn how to solve multiplication problems by drawing pictures in groups. They review the concepts of factors and products, as well as the commutative property of multiplication.

This video describes the unique properties of right triangles. It explains that every right triangle has one right angle, two legs, and one hypotenuse. It also emphasizes that the size and orientation of right triangles can vary, but...

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...

This video shows how a student named Jack solved a math game called "Missing Angles" at a unique math fair. The game involves finding the right values for angles in different shapes of quadrilaterals, and Jack used basic knowledge of the...
