How to use Graphing Calculator
- Type an equation such as y = sin(x), x^2 + y^2 = 25 or y > x^2, or add a parametric curve.
- Drag to move, pinch or scroll to zoom, and tap the graph to trace values.
- Read roots and intersections in the panel, then export a PNG or SVG.
What are the limits of Graphing Calculator?
Plots on your device from the expressions you type; nothing is uploaded. Curves are sampled, so very sharp spikes can be missed and roots are found only inside the visible window. Roots and intersections are listed for y = f(x) lines only.
