Recently the world's population passed seven billion and it continues to grow by 200,000 people every day. Listen to some reasons why our population is growing at such a rate, and the strain this will put on resources such as food and water. This clip provides context for calculations involving exponential growth.

This sequence of three lessons explores different representations of quadratic functions, with particular emphasis on turning points in quadratic graphs. Students use images of trajectories, inscribe their own curves using Geogebra and then further explore the algebraic representation of their curves. Each lesson is outlined ...

Video games have evolved over the years to become more realistic. One reason for this could be that when objects move in video games, they seem to obey the laws of physics. The software that allows for this is called a physics engine. One equation that game programmers might be using when programming their physics engine ...
