Regression Calc provides an easy way to visualize curves. Add as many points as necessary and Regression Calc will plot them on a graph for you.

Multi Translate is fast and efficient. First choose the language you want to translate from, and three other languages you want to translate to. You have more than 100 to choose from. Then either type or speak to translate. Multi Translate keeps a running history of everything you’ve translated, which is searchable via Spotlight. The app also includes iMessage support, Apple Watch support, and the ability to share results.

Why buy an expensive graphing calculator when you can have one on your iDevice for free?

It also allows you to view the values of your functions in table form, set variable start values, graph up to four functions simultaneously, and present results in either portrait or landscape orientations.
