A quadratic equation is drawn as a curve on a set of axes. This type of curve is called a parabola and it is symmetrical. To draw the graph we need coordinates. We generate these coordinates by ...

Graphs can also be used to evaluate more complex expressions, such as those involving multiple functions or operations. The ...

Try matching the following graphs with their corresponding function types: A periodic wave that oscillates between -1 and 1.

A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...

Google's latest animated Doodle celebrates the quadratic equation, transforming its homepage into an interactive classroom. This visual tribute highlights the formula's components and solutions, ...

In a [previous post](/dotphysics/2008/09/basics-making-graphs-with-kinematics-stuff-part-ii/), I talked about how to plot kinematics data with a spread sheet and how ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas. His ...
