The gradient of a line tells us how steep the line is. Lines going in this / direction have positive gradients, and lines going in this \ direction have negative gradients.



The gradient can be found by finding how much...

In this video, students learn about the transformations of sinusoidal functions by shifting their graphs horizontally and vertically. They explore how changing the values of K and H in the equations of sine and cosine functions affect...

This video goes over the similarities and differences between two inequalities, highlighting the importance of understanding the inequality signs and the order of the variables. We emphasizes the need to carefully graph the inequalities...

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.

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...

Perpendicular Lines

In this lecture, the speaker explains how to use the logarithmic graph to estimate parameters in the form of KB to the power of X. The speaker shows how to take the logarithm of both sides of the equation to bring X down out of the way,...

Reciprocal functions are actually extremely important. Isaac Newton deduced that the forces needed to hold planets in orbits is a reciprocal relationship with the squares of their distances. Radioactive isotopes decay reciprocally, and...

Use this quick calculator trick to help you generate the table of values, giving you the coordinates to plot onto a graph. Your calculator saves you time, and means you will not make mistakes substituting in values into the equation.

This video explains the fundamental concepts of time, distance, speed, and acceleration, and how they are related to each other. It also demonstrates how different factors like traffic, slope, and road type can impact the time and speed...

Here we are going to look at Velocity-time graphs. These are graphs which look at the change of velocity over time. It may be useful for you to look at our video on distance-time graphs before starting this video.

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...

This video provides tips for creating effective visual aids in PowerPoint presentations, emphasizing the importance of using visuals to reinforce messages and engage audiences. The presenter offers best practices for slide development,...

Working with absolute values.

It explains how to interpret and construct a linear graph. It also explains dependent and independent variables.

This video is a lecture presentation on velocity time graphs. The presenter shows a graph with velocity on the Y-axis and time on the X-axis and explains the key characteristics of the graph, including constant acceleration and...

To find the equation of a straight line from a graph, you first need to find the gradient and then secondly find the y-intercept.



The equation of a straight line is y=mx+c, where m is the gradient and c is the...

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.
