Taculator 84 Graphing Calc

FOUR WAYS TO GRAPH • Polar, Parametric and Sequence graphing join Function mode. Switch in MODE and everything follows: window variables, trace, tables, CALC values like dy/dx and dr/dθ, and zoom • Sequences u, v, w with TIME plots, WEB cobwebs and phase plots A NEW FACE • Press ⌂ for the icon home screen: every tool one tap away • Every menu and settings screen has been redesigned, with a cleaner look and pill-style choices • Optional status line shows NORMAL FLOAT AUTO REAL RADIAN at a glance, plus a canvas switcher for side-by-side calculations CONICS & LINES, REBUILT • Pick an equation template (E1 to E6) and type the values right into the equation • Lines join the conics, including the vertical line X=C that Y= can never draw • Graph several equations at once in their own colors. SOLVE still prints center, foci, vertices, directrix and asymptote slopes STATISTICS THAT GUIDE YOU • Every test, interval and distribution wizard got clear input fields and a real CALCULATE button • Manual-Fit: fit your own line with the cursor. QuickPlot & Fit-EQ: drop points on the graph and fit a model right there SMALL THINGS YOU'LL FEEL EVERY DAY • Error messages appear right under your input line, with the exact spot highlighted • A smarter cursor: placeholder boxes in templates, and the arrow keys walk fraction and integral fields • Points of Interest appear while you trace, so the plain graph stays clean • Prefer French key labels? MODE ▸ KEYCAPS: FRANÇAIS Previous update: • The graph screen learned to see: Points of Interest trace, one-finger graph scrolling, the complete ZOOM and DRAW menus, pictures and background images
