Scientific Calqon

Correct precedence and implicit multiplication, trig and hyperbolics, logs, roots, factorials, nCr/nPr, and constants π, e, τ, φ.

1/3 + 1/6 → 1/2 and √8 → 2√2 — exact fractions and radicals with no floating-point rounding.

d/dx, d²/dx², and ∫ dx with integration by parts, substitution and partial fractions — plus definite integrals.

Exact linear and quadratic roots, and all complex roots of any-degree polynomials — solve(x³−1) → 1, −½ ± (√3/2)i.

y = f(x), parametric and polar plots on a live canvas with pinch-zoom, pan, trace and auto grid.

Determinant, inverse, transpose, RREF, rank, eigenvalues and eigenvectors — and Ax = b solved exactly.

Enter i and compute — (2+3i)(1−i) = 5+i, √(−4) = 2i, e^(iπ) = −1, with abs, arg, conj, re and im.

Mean, median, variance, regression, and normal, binomial, Poisson and t distributions.

Live conversion across 11 categories, plus 17 physical and mathematical constants — tap to copy.

MC / MR / M+ / M−, Ans recall, copy result, and a persistent history — tap any entry to reuse it.

Two-sided limits, Taylor series expansion, and step-by-step explanations for derivatives.

A cyan-indigo glow at night, a crisp clean look by day — switch in one tap, saved automatically.
