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 steps. This video...

👉 Learn the basics of graphing a tangent and a cotangent function. To plot the tangent and the cotangent graph we choose a set of points and form a table of values with which we plot the points on the x-y coordinate axis to obtain the...

👉 Learn the basics of graphing trigonometric functions. The graphs of trigonometric functions are cyclical graphs which repeats itself for every period. To graph the parent graph of a trigonometric function, we first identify the...

The aim of this video is to explore area charts. This clip is from the chapter "Excel 2019 Advanced: Graphs and Charts" of the series "The Complete Excel Guide: Beginners to Advanced".In this section, we'll explore graphs and charts.

👉 Learn all about graphing logarithmic functions. A logarithmic function is a function with logarithms in them. The graph of the parent function of a logarithmic function usually takes its domain from the positive x-axis. To graph a...

👉 Learn how to divide two functions. We will explore the division of linear, quadratic, rational, and radical functions. To divide two functions, we simply algebraically divide the rules (contents) of the two functions. We will then...

The video is a lecture presentation on the topic of reflections of graphs. The presenter explains the concept of reflection and how and why graphs get reflected in the X or Y axis using mirror lines. They use examples to explain the...

Define Piecewise Function Notation

Learn all about solving absolute value equations. We will explore what makes up an absolute value symbol, what steps to follow when solving, how to know when you have extraneous solutions and how to set up two cases.

In this video, the teacher explains how to use a bar graph to solve put-together problems. By organizing data into categories and labeling the axes, students can visually represent information and find solutions. The teacher provides...

In this video, the presenter analyzes two graphs that represent the same journey: a distance time graph and a velocity time graph. The graphs are divided into clear sections and compared to show how each one tells the story of the...

This video demonstrates how to use spark lines in Microsoft Excel to visually represent data trends efficiently. Spark lines are miniature graphs embedded within cells, providing a quick and clear overview of patterns in student scores...

This video explains how to use a picture graph to solve compare problems. It teaches different strategies to find the difference between categories in the graph, such as comparing side by side or subtracting.

This video is a lecture presentation on distance time graphs for accelerated motion. The presenter explains the basics of distance time graphs and how they depict the speed of an object. The presentation then moves on to discuss...

👉 Learn about graphing linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. i.e. linear equations has no exponents on their variables. The graph of a linear equation is a straight line. To...
