Learn how to write the equation of a parabola given the vertex and the focus. 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). Recall...

👉 Learn how to graph linear equations written in standard form. When given a linear equation in standard form, to graph the equation, we first rewrite the linear equation in slope intercept form, (i.e. in the form y = mx + c, where m is...

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 find the distance between two points. The distance between two points is the length of the line joining the two points in the coordinate plane. To find the distance between two points in the coordinate plane, we make use...

The video is about stationary points and how to find them using differentiation. The presenter starts by discussing the graph of a function and how to find its gradient by drawing the tangent. They then identify the stationary points as...

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...

Master how to determine if a graph is a function or not

The video discusses the role of managers and the different tasks and responsibilities they have in different industries, such as business, sports, films, and music. It highlights the importance of managers in coordinating and controlling...

This video lesson introduces/reviews how to graph a quadratic function in standard form.

👉 In this playlist you will learn how to graph a linear equation in standard form, slope intercept form as well as when the slope and y intercept are provided. In addition to graphing linear equations we will also learn how to determine...

👉 Learn how to find the point on the unit circle given the angle of the point. A unit circle is a circle whose radius is 1. Given an angle in radians, to find the coordinate of points on the unit circle made by the given angle with the...

In this lesson, students will learn how to find distances between points in space using a coordinate plane. They will understand how to plot and read points on the plane, and how movement on the plane corresponds to cardinal directions.

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

👉 Learn how to apply transformations such as translations, rotations, reflections as well as dilation to points, lines, triangles, and other shapes. When applying transformations we will use certain rules as well as tricks to help you...

👉 Learn how to find the inverse of a function. The inverse of a function is a function that reverses the "effect" of the original function. One important property of the inverse of a function is that when the inverse of a function is...

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...

Master Determing if a set of points is a Function or Not

4d Warm up

👉 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...

Just as the Cartesian plane allows sets of ordered pairs to be graphically displayed as 2-dimensional objects, Cartesian space allows us to visualize sets of ordered triples in three dimensions.

Perpendicular Lines

In order to mathematically describe a line in 3-dimensional space, we need a way to define the values of the three coordinates at every point along the line. This can be done by creating a group of "parametric equations".

Master Solving a system of equations by graphing

Watch this video to discover how to plot straight lines onto a graph.



Start by creating a table of values, choosing values of x to substitute in to the equation, to get the corresponding value of y. This will generate...
