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

THE GRAPH SCREEN LEARNED TO SEE • Points of Interest trace: zeros, maxima, minima and intersections snap right under your crosshair while you trace — asymptotes too. Turn it on under FORMAT ▸ DETECT • Scroll the graph with one finger — drag the window wherever you like, and the GRAPH key snaps it right back home • The complete ZOOM menu: ZBox, Zoom In/Out, ZSquare, ZDecimal, ZTrig, ZInteger, ZoomFit, ZoomStat and fraction presets — plus zoom factors, ZPrevious, ZoomSto and ZoomRcl on the new MEMORY tab • FORMAT grew from 3 to 8 settings: grid, axes, labels, coordinates, expressions and more • Full support for piecewise functions. A COMPLETE DRAW MENU • Write Text( on the graph, doodle with Pen, set points and pixels, drag an interactive Circle( • Store and recall ten pictures (Pic1–Pic0) — or put any photo behind your graph as a background image • Shade( fills the region between two curves, and the distribution menu gained a DRAW tab: ShadeNorm, Shade_t, Shadeχ², ShadeF DEEPER STATISTICS • Three new regression models: PropReg, RecipReg and eBASEReg SMALL THINGS YOU'LL FEEL EVERY DAY • Fraction results now show little blue ◄► arrows — tap them to flip between fraction and decimal • New MODE options: ANSWERS (auto/decimal/fraction), FRACTION TYPE (n/d or Un/d) and the GRADIAN angle mode • New commands: seq(, ΔList(, augment(, ClrAllLists, storing to dim( • VARS menu now covers window, zoom and statistics variables, GDBs, pictures and Y-VARS • Every zoom command is in the Catalog with a description of how it sets your window Previous update: • The apps key went live — Geometry, Polynomial Root Finder, Finance, Probability Simulation, Science Tools, Transformation Graphing, Conics, Inequality Graphing and the Periodic Table
