Graphing calculator

Plot one, two, or three functions of x on an adjustable Cartesian grid.

Functions: sin, cos, tan, asin, acos, atan, sqrt, ln, log, abs, exp, floor, ceil, round. Constants: pi and e. Write multiplication explicitly, such as 2*x.

Plot functions on a Cartesian grid

Enter up to three expressions using x as the independent variable. The calculator evaluates each expression across the visible horizontal range and maps finite real results to the selected vertical range. Grid lines, tick labels, and axes provide scale. Each function uses a different color and appears in the legend below the graph.

Supported expression notation

Use explicit operators: +, −, *, /, %, ^, and factorial. Parentheses control order. Functions include trigonometry, inverse trigonometry, square root, natural and base-10 logarithms, absolute value, exponential, and rounding operations. In radian mode, sin(pi/2) equals 1; degree mode interprets sin(90) as 1.

Discontinuities and visible ranges

The plot samples many x-values and breaks the line when a result is not finite or jumps far outside the visible graph. This reduces—but cannot eliminate—false connections across asymptotes. Narrower ranges reveal more detail. A graph is a numerical approximation and can miss roots, extrema, oscillations, holes, or behavior between samples.

This tool draws real-valued explicit functions y = f(x). It does not solve equations, prove properties, plot implicit or parametric relations, or replace validated mathematical software for consequential work.
