What You Can Plot

This graphing calculator handles everything from basic algebra to advanced calculus and statistics.

Functions and Equations: Plot linear, quadratic, polynomial, exponential, and logarithmic functions. See the curve the moment you type.

Trigonometric Graphs: Graph sine, cosine, tangent and their inverses. Switch between degree and radian mode instantly.

Multiple Equations at Once: Plot several equations on the same coordinate plane and compare their behavior side by side.

Piecewise Functions: Use curly brace notation to graph piecewise functions cleanly without workarounds.

Regression and Data Analysis: Enter a data set, fit a linear or quadratic model, and visualize the line of best fit with your scatter plot.

Parametric and Polar Graphs: Go beyond standard Cartesian coordinates for engineering, physics, and advanced coursework.

Save and Export Graphs

Every graph you plot can be exported as a PNG image. Drop it directly into a report, thesis, assignment, or presentation. No screenshot tools needed.

Who Uses This Tool

High school students use it for algebra, pre-calculus, and trigonometry homework. It covers everything a physical graphing calculator handles for daily classwork.

College students rely on it for calculus, statistics, and linear algebra. Runs on a laptop or phone, so it is always accessible.
