## What is ZetaCAS?

Type maths the way you would say it and get the exact answer, the steps that lead to it, a graph and a check. ZetaCAS is a full computer algebra system that runs entirely on your device: no account, no ads, no internet needed, and nothing you type ever leaves your phone, tablet or Mac. 

WRITE IT YOUR WAY
• Plain words or notation: "integrate x^2 sin(x) dx", "∫ e^(-x^2) dx from 0 to oo", "lim (1+1/n)^n as n->oo", "d/dx x^x".
• Typos are fine: "derivarive" and "intgeral" land on the right operation.
• Also understands many questions in Spanish, such as "derivar x^2+3x+2".
• Type a bare function like x^2+3x+2 and get everything at once: graph, domain, range, roots, extrema, asymptotes, derivative and integral.

EXACT ANSWERS, WITH THE WORKING
• Step by step: integration by parts and substitution, the chain rule, series expansions for limits, the quadratic formula.
• Answers are checked: an integral is differentiated back to the integrand.
• Exact first: √π/2, π²/6, (5 ± √5)/2. Then the decimal, with as many digits as you ask for.
• Honest numbers: an estimate says it is one (0.39095 ± 7e-05), and a long computation shows only the digits that are really correct.

WHAT IT CAN DO
• Calculus: derivatives of every kind, definite, indefinite and improper integrals, limits, Taylor and Laurent series, Riemann sums, arc length, area between curves, tangent lines, optimisation.
• Equations: polynomials of any degree with every real and complex root, systems, inequalities, recurrences, differential equations, Lambert W and many special functions....
• Algebra: factor, expand, simplify, partial fractions, complete the square, polynomial division.
• Matrices and vectors: determinant, inverse, eigenvalues and eigenvectors, row reduction, LU and QR, matrix exponential, Jacobian, Hessian, gradient, divergence and curl.
• Transforms: Laplace, Fourier series and transform, z-transform, Hilbert transform, convolution.
• Probability and statistics: eleven distributions, quantiles, p-values, regression, histograms and box plots.
• Number theory: primes, divisors, gcd, modular arithmetic and congruences, totient, number bases, continued fractions, gamma and zeta functions.
• Discrete maths and logic: counting, sets, truth tables, CNF.
• Complex numbers: the Argand plane, polar form, domain colouring, every root of a polynomial drawn on the complex plane.
• Geometry and trigonometry: polygons, triangles, distance and slope, degrees or radians.

GRAPHS YOU CAN EXPLORE
• Functions, implicit curves, polar and parametric curves, surfaces and slope fields.
• Zoom, pan and hover to read exact points; roots, turning points and holes are marked.

MADE FOR STUDYING
• Every result can be copied as LaTeX.
• Your history stays on the device.
• Light and dark themes that follow your system.
