Loading Graphing Calculator
Plot equations and graph functions instantly in your browser — quadratics, sine waves, lines, circles, inequalities and more. A fast, free Desmos-style graphing calculator built for students. No download, no sign-up, works on phone and laptop.
This free online graphing calculator lets you plot equations and visualize math the moment you type them. Whether you need a quick desmos graphing calculator for homework, want to graph functions online for a class project, or are practicing for an exam, everything runs right in your browser. There is nothing to install, no account to create, and it loads instantly on a phone, tablet, Chromebook or laptop.
Students use it to graph linear equations, draw parabolas, explore trigonometric curves, test inequalities and check answers in seconds. Type an equation like y=x^2 and the graph appears live — then zoom, pan, and add as many functions as you like.
Type any equation and see the curve immediately — linear, quadratic, polynomial, trig, exponential and more.
A mobile-friendly graphing calculator with touch zoom and pan. No app store, no download required.
Layer many functions on one grid to compare graphs and find intersection points visually.
Download a screenshot of your graph as a PNG for homework, notes or your study group.
New to graphing calculators? You can plot your first function in under a minute:
y=x^2 to graph a parabola.y=x^2 or y=ax^2+bx+c to draw a parabola.y=2x+3 to plot a straight line and see its slope and intercept.y=sin(x) or y=cos(x) for trig waves.x^2+y^2=25 for a circle of radius 5.y>x^2 to shade the solution region.This online graphing tool handles the full range of functions students meet from algebra through calculus:
Graph lines, slopes, parabolas and find roots and vertices.
Plot cubic, quartic and higher-degree curves with multiple turning points.
Sine, cosine, tangent and their transformations — amplitude, period, phase shift.
Graph growth, decay and log curves like y=2^x and y=log(x).
Shade solution regions for linear and nonlinear inequalities.
Circles, ellipses, parabolas and hyperbolas from implicit equations.
Define functions over intervals and graph them on one grid.
Plot parametric paths and polar curves for advanced math.
The digital SAT includes a built-in graphing calculator, so practicing with an online graphing calculator before test day is one of the best ways to get faster at the math section. Use this tool to rehearse graphing equations, finding intersections, and reading solutions visually — exactly the skills the exam rewards.
Because it is free and runs in any browser, you can practice at home, in the library, or on your phone between classes — no expensive handheld calculator needed.
Looking for a free graphing calculator that works like the ones you use in class? This tool gives you instant, browser-based graphing with a clean interface that students already know. It is a great free alternative when you do not want to install software, create an account, or pay for a graphing app.
Compared with a physical graphing calculator, an online graphing calculator is free, always up to date, easier to read on a big screen, and impossible to lose. Compared with downloadable math apps, it loads instantly and works on any operating system.
Explore the most-searched things students do with an online graphing calculator:
| If you want to… | Type this |
|---|---|
| Graph a parabola / quadratic | y=x^2 |
| Graph a straight line | y=2x+3 |
| Graph a sine wave | y=sin(x) |
| Graph a cosine wave | y=cos(x) |
| Graph a circle | x^2+y^2=9 |
| Graph an exponential function | y=2^x |
| Graph a logarithm | y=log(x) |
| Graph an inequality | y>x^2-1 |
