In this video, Leandre conducts an experiment to determine if different types of sunlight can affect the speed of a plant's growth. This experiment highlights the importance of sunlight timing in plant growth and provides insights into...

In this video, we discuss the 6 major classes of synovial (diarthrotic) joints, along with relevant examples, movements allowed, and other critical features.

This video is a comprehensive review of the coordinate plane, including vocabulary words, quadrants, ordered pairs, and graphing points. The teacher provides clear explanations and examples, making it easy for students to understand and...

Learn how to write the equation of hyperbolas given the characteristics of the hyperbolas. The standard form of the equation of a hyperbola is of the form: (x - h)^2 / a^2 - (y - k)^2 / b^2 = 1 for horizontal hyperbola or (y - k)^2 / a^2...

In this video, the teacher explains how to determine the number of lines of symmetry in regular polygons. They discuss the three options for line symmetry: horizontal, vertical, and diagonal. Using examples of an equilateral triangle,...

In this video, students learn about the properties of congruence and how to determine if two figures are congruent using reflections. The video explains the concept of reflections, including how size and shape stay the same while...

👉 Learn how to graph quadratic equations in vertex form. A quadratic equation is an equation of the form y = ax^2 + bx + c, where a, b and c are constants. The graph of a quadratic equation is in the shape of a parabola which can either...

This video explains how to graph a proportional relationship using a table. Understand the concept of proportions and learn how to plot points on a coordinate plane. The lesson also includes a real-life example of calculating earnings...

Learn how to classify conic sections. A conic section is a figure formed by the intersection of a plane and a cone. A conic section may be a circle, an ellipse, a parabola, or a hyperbola. The general equation of a conic section is given...

The two skyscrapers were both designed around two vertical systems that were held together by a weaker horizontal link.

Projectile motion is composed of a horizontal and a vertical component. This video shows that via a side-by-side video demonstration and also builds the velocity and acceleration vector diagram.

👉 Learn about graphing absolute value equations. An absolute value equation is an equation having the absolute value sign and the value of the equation is always positive. The graph of the parent function of an absolute value equation is...

Learn all about hyperbolas. A hyperbola is a conic section with two fixed points called the foci such that the difference between the distances of any point on the hyperbola from the two foci is equal to the distance between the two...

Learn how to write the equation of hyperbolas given the characteristics of the hyperbolas. The standard form of the equation of a hyperbola is of the form: (x - h)^2 / a^2 - (y - k)^2 / b^2 = 1 for horizontal hyperbola or (y - k)^2 / a^2...

Here we solve for the speed of a plane using polar coordinate formulas.

Master How to Find the Distance Between Two Points

👉 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...

Things don't always move in one dimension, they can also move in two dimensions. And three as well, but slow down buster! Let's do two dimensions first. You know, like a cannonball. Isn't this getting fun?

What is an asymptote? An asymptote is a line which continually approaches a curve. The curve gets really really really close to the line but it never quite touches it... why? In this video, we learn all about what an asymptote is.

Identify lines of symmetry in regular polygons.

Universal Gravitational Potential Energy is introduced and graphed. It is compared to the force of gravity. And the “zero line” is defined.

Learn how to graph hyperbolas. To graph a hyperbola from the equation, we first express the equation in the standard form, that is in the form: (x - h)^2 / a^2 - (y - k)^2 / b^2 = 1 for horizontal hyperbola or (y - k)^2 / a^2 - (x - h)^2...

👉 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...
