GRAPH PRO
Advanced Graphing Calculator
An online graphing calculator is a tool that plots mathematical functions on a coordinate plane and helps you analyze them visually. Our free graphing calculator lets you plot any function of x — polynomials, trigonometric, exponential, logarithmic — and instantly see its shape. It supports zooming, derivative computation, numeric integration, and root finding. It is ideal for students learning calculus, teachers demonstrating concepts, and professionals visualizing data.
Type a function such as x^2, sin(x), or exp(x) into the input field and click PLOT. Use ZOOM IN and ZOOM OUT to adjust the scale, or press d/dx to compute the derivative, ∫dx to integrate over a range, and ROOTS to find x-intercepts. The graph updates instantly and the coordinate grid helps you read values precisely. You can also switch to CALC, SOLVE, MATRIX, or STATS for other tasks.
Graphing calculators are essential for understanding functions, but physical devices are costly and dedicated apps can be heavy. Our tool runs in the browser, needs no installation, and combines graphing with a full scientific calculator. It supports derivatives, integrals, and roots — features often locked behind paywalls. It is free, fast, and works on phones, tablets, and desktops.
Any function of x supported by math.js, including polynomials, sin, cos, tan, log, ln, exp, sqrt, and absolute value.
Yes. Click d/dx and the symbolic derivative of the current function will be shown.
Yes. Click ∫dx, enter bounds a,b, and the tool approximates the integral numerically.
Use the ZOOM IN and ZOOM OUT buttons below the graph to change the scale.
Yes, the graphing calculator is completely free with no signup.
