What is the Graphing Calculator?
Plot any mathematical function instantly in your browser — polynomials, trigonometric functions, exponentials, logarithms and more — with pan, zoom and multiple functions graphed together on the same axes. Type an equation like y = x^2 - 4 or y = sin(x) and see it plotted immediately.
Built for the same use cases as a graphing calculator app or physical device: exploring function behavior, finding roots and intersections visually, and building graphs to save, share or use for homework and teaching.

Yes, completely free with no signup required to plot and explore graphs.
Can I graph more than one function at a time?
Yes, add multiple equations and they're plotted together on the same axes.
Can I save my graphs?
Yes, save graphs to revisit them later in My Graphs, and share a link to any saved graph.
What kinds of functions can I plot?
Polynomials, trigonometric, exponential, logarithmic and most standard mathematical functions.
Do I need an account?
No, you can plot and even save graphs as a guest, though logging in keeps them permanently.
