Ascendant Graphing Calculator
A full-color graphing studio. Keep the familiar handheld on the left — or work on the big interactive board: type functions live, drag parameter sliders and watch the family of curves animate, pan, zoom, and trace with your mouse, overlay a derivative, area, or tangent line, and read a function's roots, intercepts, and turning points at a glance.
Quick examples
Studio Graph Board
Drag to pan · scroll to zoom · double-click to frame · hover for coordinates · Point mode drops a labeled point on the nearest curve.
Functions
Type any function — it graphs as you go. Click the swatch to recolor, the eye to hide, ✕ to clear. Use a letter like a, k, b and a slider appears below.
Parameters — drag or ▶ to animate

How to use it
- On the right: type functions, drag sliders, then read the insight card. On the device: press
Y=, type, thenGRAPH. X,θ,nis the variable,^powers,x²squares. Functions:sin cos tan,log(base 10),ln,abs(),sqrt(),π,e.- Board: drag to pan, scroll to zoom toward the cursor, double-click to frame curves. Trace snaps to a curve; Point drops a labeled coordinate.
- Sliders: any single letter (not x) becomes an animatable parameter — great for seeing how
