Real functions of one variable; angles in radians. Everything is calculated in your browser; nothing you type is uploaded.
Expressions are parsed by a small evaluator without eval, sampled at 600 points, drawn as SVG paths that break at discontinuities; zeros are found by sign change and bisection.
sin(x), x²/4 − 1 and 0.5x + 1 are drawn from −2π to 2π; x²/4 − 1 crosses zero at −2 and 2.
