Graphing Calculator for Windows

Plot Multiple Functions in One View

A graph command can include more than one expression and an explicit x-range. This makes it practical to compare functions instead of opening separate graph windows. For a simple comparison, enter:

graph sin(x), cos(x) from -10 to 10

Each plotted function appears in the graph legend with its own color and visibility control. You can hide or show a curve from the graph interface while keeping the other functions in view. Zoom, pan, and reset controls help you move from a broad view to a useful local one.

Inspect and Pin Coordinates

Move near a visible curve to inspect its function label and an approximate coordinate. Click an inspected point to keep the coordinate pinned while you continue exploring the graph. A pinned coordinate can also be copied as reusable text.

An explicit range helps put the important part of a graph on screen. The following quadratic has two real roots and a visible minimum in the selected range:

graph x^2 - 4*x + 3 from -2 to 6

For a guided introduction to quadratic graphs, follow How to Graph a Parabola on Windows. For a broader comparison workflow, use the multiple-function graph tutorial.

Verified Graph Commands to Try

These current SumWise commands cover general plotting and focused visual calculus workflows:

graph sin(x), cos(x) from -10 to 10
graph x^2 - 4*x + 3 from -2 to 6
graph_tangent(x^2, 3) from -2 to 6
graph_area(sin(x), 0, pi) from -1 to 4
graph_roots(x^2 - 1) from -3 to 3

The commands are intentionally explicit: they state the expression, any supported overlay inputs, and the useful range. More copy-ready commands are available on the SumWise Examples page.

Connect a Calculation to Visual Calculus

Supported graph helpers can add a tangent line, shade a definite integral region, or mark roots and extrema. The tangent workflow connects the curve, tangent point, slope, and exact tangent-line expression in the same result.

Continue with the critical-points tutorial or the Derivative and Integral Calculator for Windows guide to connect graphing with supported symbolic results.

Copy or Export the Graph

SumWise can copy the current graph as an image or save a clean, high-resolution PNG of the visible graph. The export includes the current viewport, visible curves, supported overlays, and a pinned point when present. Transient hover state and the surrounding application controls are excluded from the saved graph image.

A Local Windows Graphing Workflow

Graph calculation and interaction are designed to run locally after SumWise is installed, without depending on a browser or cloud calculation service. Microsoft Store still handles installation, trial, purchase, and license verification.

Honest Graphing Scope

SumWise graphing focuses on multiple real-valued functions, paired data plots, linear regression, and supported visual calculus overlays. It does not provide 3D graphing and is not an exam-certified handheld calculator. Symbolic and calculus helpers cover supported workflows rather than universal mathematical cases.

Graphing Calculator FAQ

Can SumWise graph more than one function?

Yes. A graph command can include multiple functions, and visible curves can be controlled from the graph legend.

Can I inspect a curve?

Yes. SumWise supports curve inspection, pinned coordinates, and coordinate copying for visible plotted curves.

Can I export a graph?

Yes. You can copy the graph as an image or save a clean PNG of the current graph view.

Does SumWise graph in 3D?

No. The current public graphing workflow focuses on real-valued 2D functions, paired data, regression, and supported overlays.
