The video explains how to write the equation of a straight line, including both horizontal and vertical lines. It highlights the importance of understanding the gradient and the Y intercept in order to write lines as Y=MX+C. The video...

The video is an educational tutorial on angles in parallel lines. The narrator explains the concept of parallel lines and how to identify them, as well as how to determine the angles created by an intersecting line. Three important...

How will we make the transition from fossil fuels to renewable alternatives? Could batteries change how you travel or power your homes? Learn about what clean energy could mean in the next decade.<br/>

This video provides an introduction to angle notations and conventions. The presenter explains what an angle is, how to measure it using a protractor, and the unit of degrees. The video discusses the importance of angles in various...

Learn to define linear functions by analyzing graphs of the forms y = x and y = mx. Understand that linear functions have a constant rate of change and that the coefficient of x, also known as the slope, determines the steepness of the...

In this video I will show you what you should expect to know before starting your chapter on Applications of Trigonometry. In applications of trigonometry we will explore solving trigonomtric word problems, law of sines, cosines,...

Learn how to solve problems with arcs of a circle. An arc is a curve made by two points on the circumference of a circle. The measure of an arc corresponds to the central angle made by the two radii from the center of the circle to the...

This video is a presentation on how to find the equation of a straight line when given some coordinates. The presenter explains that all straight lines follow the same general equation (Y=MX+C) and defines the values of M as the gradient...
