Whether you're a student learning algebra for the first time or a researcher exploring calculus, these guides will help you get the most out of the free online graphing calculator. Each guide includes step-by-step instructions with example equations you can try instantly.
How to Use a Graphing Calculator
A complete beginner's guide to using an online graphing calculator — entering equations, reading graphs, and using key features.
Graphing Linear Equations
Learn to graph y = mx + b, find slope and intercepts, plot parallel and perpendicular lines, and solve systems graphically.
Graphing Quadratic Functions
Master parabolas — vertex form, standard form, finding roots with the quadratic formula, and exploring transformations.
Graphing Trigonometric Functions
Graph sine, cosine, and tangent waves. Understand amplitude, period, phase shift, and vertical shift with interactive examples.
Calculus with a Graphing Calculator
Use graphing tools to visualise derivatives as tangent lines and compute definite integrals using the integral shading tool.
Polar Graphing Guide
Explore polar coordinates, graph roses, cardioids, limaçons, and spirals using r = f(θ) equations in polar mode.
Statistics & Linear Regression
Plot scatter data, fit a regression line, interpret slope, intercept and R² to understand trends in your data.
