We’re pleased to announce the release of our first collection of tutorials exclusively for the TI-Nspire iPad App. These PowerPoint-based tutorials walk you through the use of the App. As with our other tutorials, we focus on math concept development, not just button pushing.

The new iPad App has all the functionality of the handheld, but with a very different interface. These tutorials will walk you through that.

The first batch of tutorials cover these topics:

- Graphs of Inequalities
- Graphing a Scatterplot
- Graphs of Absolute Value Functions
- Graphs of Inequalities with Sliders
- Graphs of Linear Functions
- Graphs of Quadratic Functions in Standard Form with Sliders
- Graphs of Quadratic Functions in Vertex Form with Sliders
- Parallel and Perpendicular Lines
- Point-Slope Form
- Quadratic Formula Template
- Slope Formula
- Slope-Intercept Form with Sliders

We reproduce them here as Slideshare Presentations:

We have a number of resources on our site for teaching and reviewing quadratic equations and functions. In this Blog entry we bring them together to make it easier to find them.

## Quadratic Equations and Functions

**Math Examples**

Our Math Examples page includes hundreds of worked-out examples for a variety of algebra topics. Far exceeding the handful of examples found in textbooks, our Math Examples allow students to recognize among the solutions to better anchor their understanding of the concept.

- 10 worked-out examples for solving quadratic equations graphically: http://media4math.com/math-examples.asp#QuadraticsGraphically. Includes a quiz and a slide show.
- 4 worked-out example for solving quadratic equations by completing the square: http://media4math.com/math-examples.asp#CompletingSquare. Includes a quiz and a slide show.
- 12 worked-out examples for solving quadratic equations using the quadratic formula: http://media4math.com/math-examples.asp#QuadraticFormula. Includes a quiz and a slide show.
- 11 worked-out examples for factoring quadratics: http://media4math.com/math-examples.asp#FactoringQuadratics. Includes a quiz and slide show.
