Graphing Calculator
Plot one or more functions like sin(x) or x^2 on an interactive, zoomable graph.
Functions of x
Use x, + − * / ^, parentheses, sin cos tan, sqrt, abs, ln, log, exp, pi and e. Implicit multiplication works: 2x, 3sin(x).
Hover over the graph to trace values. Drag to pan, scroll to zoom.

How to use the Graphing Calculator
Plot one or more functions like sin(x) or x^2 on an interactive, zoomable graph.
- 1 Type functions of x in the boxes, such as x^2/4 - 2.
- 2 Drag to pan and scroll or use the buttons to zoom.
- 3 Hover over the graph to read the value of every function at that x.
Example and practical tips
Plot sin(x) and x/3 together and hover where they cross to estimate the solutions of sin(x) = x/3.
Frequently asked questions
Which functions are supported?
Powers, roots, sin, cos, tan and their inverses, logarithms, exp, abs, floor, ceil and constants pi and e.
Why are there gaps in a curve?
Gaps appear where a function is undefined, such as 1/x at x = 0 or sqrt(x) for negative x.
