Graphing Calculator

Type a function of x and see it plotted instantly, with zoom and custom axis ranges.

  1. Type a function, e.g. sin(x) * x
  2. Adjust the axis ranges or zoom
  3. Read the plotted curve

Supports + − × ÷ ^, parentheses, sin/cos/tan/asin/acos/atan/sqrt/abs/exp/log/ln, and constants pi, e. Runs entirely in your browser — no expression is ever eval’d.

Frequently asked questions

What kinds of functions can I plot?
Any y = f(x) expression, including trigonometric functions (sin, cos, tan), roots, logarithms, exponents and standard arithmetic — for example sin(x) * x or sqrt(x) + 2.
How do I zoom or change the axis ranges?
Use the zoom controls to scale the view, or manually set custom minimum/maximum values for the x and y axes to focus on a specific region of the curve.
Can I plot more than one function at once?
Enter a function to see it plotted; check the tool for whether multiple functions can be layered on the same graph for comparison.
Is my function or data sent to a server?
No. Parsing and plotting happen entirely in your browser — nothing you type is uploaded or stored.
Do I need to install anything or sign up?
No. It runs entirely in your browser — no software install, no account, no email required.
