Description

Explore math with Downy! Graph functions, create function tables, explore transformations, plot points, animate your graphs, and more – for free!

With Downy, we imagine a world of universal math literacy and envision a world where math is accessible and enjoyable for all students. We believe the key is learning by doing.

To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and amazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Sliders make it a breeze to demonstrate function transformations. It’s intuitive, beautiful math.

Features:

* Graphing: Plot polar, Cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time – and you don’t even need to enter expressions in y= form!

* Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph

* Tables: Input and plot data, or create an input-output table for any function

* Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window.

* Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger.

* Scientific Calculator: Just type in any equation you want to solve and Downy will show you the answer. It can handle square roots, logs, absolute value, and more.

* Inequalities: Plot Cartesian and polar inequalities.

* Offline: No internet access required. Great for classroom use!
