Mathematics with PocketCAS Pro

PocketCAS now supports iPhone Duo. On iPhone Duo: - Open in landscape, and your document sits on the left page. The right page holds the editor with the math keyboard, or a plot. - Tap a plot in your document to open it on the right page, next to your calculations. When you edit a plot, it redraws as you type. - In full screen, a plot's buttons and legend sit in the vertical bar, out of the plot's way. - Open in portrait or in tabletop pose, the text is on the upper half and the keys are on the lower half. In tabletop pose, a plot stands on the upper half, with its functions, the traced point and the value table below it. - If you want the document across both pages, choose Wide Document in Settings > iPhone Duo > When Open. - Closed, PocketCAS works as on any other iPhone. On every iPhone and iPad: - With a hardware keyboard, Tab moves to the next argument only inside brackets. Elsewhere it types a tab, so you can indent comment lines again. If something works differently from what you are used to, or you find a problem, please write to me.
