A graphing calculator is one of the most useful tools a math student can have. It turns abstract equations into visual curves, helping you spot roots, intercepts, asymptotes, maxima and minima at a glance. This free online graphing calculator lets you plot any function — linear, quadratic, cubic, trigonometric, logarithmic, exponential — directly in your browser.
Type something like sin(x), x^2 - 4, log(x) + 2 or e^(-x)*cos(x) and the curve appears instantly. Add multiple equations to compare shapes side-by-side, then zoom and pan to focus on any region of interest. It works perfectly on Chromebook, Windows, Mac, iPhone and Android — anywhere a modern browser runs.
Pair it with our TI-84 Calculator Online for scientific calculations, the GPA Predictor to track your math grades, the Marks Needed Calculator to plan for your next test, and the Percentage Calculator for quick conversions.
Studying for a big exam? Use the Study Time Calculator and Exam Countdown Timer to stay on schedule, and check our student study blog for tips on tackling algebra, calculus and statistics.
Yes — completely free, no sign-up required, no download. It runs entirely in your browser and you can use it as many times as you want.
You can plot linear, quadratic, cubic and higher polynomials, trig functions (sin, cos, tan and inverses), hyperbolic (sinh, cosh, tanh), logarithms (log base 10 and ln), exponentials, square roots and absolute value functions.
Click the 'Add' button in the equations panel. Each new function gets its own color, and you can toggle individual graphs on and off using the colored circle next to each equation.
Yes — use the Window panel to manually set x min, x max, y min and y max. You can also use the Zoom In, Zoom Out and Reset buttons for quick adjustments.
Absolutely. The graph canvas auto-resizes to fit your screen and works on Chromebook, iPad, iPhone and Android in any modern browser like Chrome, Safari, Edge or Firefox.
Use ^ for powers — for example x^2 for x squared, x^3 for x cubed. Use sqrt(x) for square root and x^(1/3) for cube root.
