Equation Graph Generator | Plot y = f(x)

Plot up to 3 simultaneous y = f(x) equations on a shared axis. Supports polynomials, trig, logs, exponentials, and more. Download as PNG or copy to clipboard.

Parametric Curve Grapher | x(t) y(t)

Plot parametric curves defined by x(t) and y(t) and download the graph as PNG.

Polar Graph Generator | r(θ)

Plot polar equations r(θ) including roses, spirals, and limaçons. Download as PNG.

Bezier Curve Calculator | De Casteljau Algorithm & Curve Points

Compute quadratic and cubic Bezier curves using the De Casteljau algorithm. Enter control points, choose any parameter t ∈ [0, 1], and see every intermediate interpolation step. Generates a full table of (x, y) coordinates along the curve, computes the tangent vector, and shows the first and second derivative formulas.

About Graphing & Visualization Calculators

Graphing and visualisation tools let you see mathematical functions as curves, surfaces, and plots. Visual representation is often the fastest way to understand the behaviour of a function, where it crosses zero, reaches a maximum, or oscillates.

Who uses these tools: Students checking their calculus homework, engineers visualising design constraints, teachers preparing demonstrations, and anyone who wants to see what an equation "looks like" before working with it algebraically.

Tips for best results: If a graph looks unexpected, check the domain and range settings. A function that appears flat may be plotted on a scale too large to show its variation; one that appears to have discontinuities may just need a wider x-range to show the full curve.
