What can the graphing calculator plot?

Functions of x, parametric curves (x(t), y(t)), polar curves (r(θ)), inequalities and statistical plots like histograms, scatter plots and box plots.

How do I plot multiple curves at once?

Add each function as a separate entry. Each is drawn in a different colour with a legend, and you can zoom and pan to inspect intersections.

Can it find roots and intersections?

Yes. Click any point on a curve to read its coordinates, and use the analysis menu to find zeros, extrema and intersections numerically.

About This Calculator

The Graphing Calculator is a full-featured mathematical tool with over 800 functions across five integrated modules — all running entirely in your browser with no data stored or shared.

Graph Module

Plot up to 6 simultaneous functions in Function, Polar, or Parametric mode. Use zoom controls, drag to pan, or scroll to zoom. Window settings (Xmin, Xmax, Ymin, Ymax) give full control over the viewing area. Preset windows include Standard (−10 to 10), Trig (−2π to 2π), and Quadrant 1.

Scientific Calculator Module

Extended scientific calculator with 30+ function keys including:

Trigonometry: sin, cos, tan and their inverses; hyperbolic sinh, cosh, tanh and inverses
Logarithms: log (base 10), ln (natural log), log₂ (base 2)
Powers and roots: xʸ, x², √x, ∛x, 1/x
Combinatorics: n!, nCr (combinations), nPr (permutations), gcd
Constants: π, e, φ (golden ratio 1.618…)
Calculus: numerical derivative d/dx and definite integral ∫ at a point
Memory: MS, MR, M+, M−, MC with 5-register memory
Display modes: Normal and Scientific notation

Statistics Module

Enter a dataset and instantly compute 16 descriptive statistics: n, sum, mean, median, mode, range, min, max, Q1, Q2, Q3, IQR, population SD, sample SD, variance, and Σx². Run 5 regression models: linear, quadratic, exponential, power, and logarithmic — each showing the equation and R² correlation coefficient.

Matrix Module

Build two matrices (A and B) up to 4×4 and perform: addition, subtraction, multiplication, inverse (A⁻¹), determinant, transpose, and Reduced Row Echelon Form (rref). Results are displayed in formatted grid layout.

Table of Values Module

Generate a complete table of values for any function f(x). Set the start, end, and step size. Supports all mathematical functions available in the calculator. Undefined values (e.g. 1/0) are clearly marked.

Important Note: This tool is intended for educational and reference purposes. Numerical derivatives and integrals use approximation methods and may carry small rounding errors. Always verify critical results with a qualified professional.
