Online Graphing Calculator interactive tool
Use x, numbers, parentheses, +, -, *, /, %, ^, and functions such as sin(x), sqrt(x), and abs(x).
What Is Online Graphing?
A graph plotter or online graphing calculator lets you enter a function f(x) and immediately see its curve on a coordinate plane. Visualizing graphs helps students build intuition about slope, curvature, intercepts, and asymptotic behavior.
Why Use a Graph Plotter Instead of Only Manual Sketching?
Manual sketches are useful for building intuition, but a graph plotter makes it easier to inspect a curve over a chosen x range. This graphing calculator samples one-variable expressions such as sin(x) or x*x and draws the resulting curve on a coordinate plane.
How To Use the Online Graphing Calculator
- Enter a function of x using the supported math syntax, such as x*x, sin(x), or exp(x).
- Set the x-min and x-max values to define the interval you want to view on the graph.
- The graph plotter will sample the function across that interval and display a smooth curve on the coordinate plane.
- Adjust the range or change the function to explore different shapes and behaviors.
- Use the Example button to load a sample function like sin(x), or Reset to clear the inputs.
Plot an equation or function online
This graphing calculator plots one supported function of x over a selected interval, including common algebraic and trigonometric expressions. It is useful for inspecting a curve before solving or comparing it with a hand-drawn graph.
