Learn all of maths, in order.

From counting to the open problems. Pick where you are; every lesson shows its steps, draws the picture, and hides the answer until you ask.

Or bring your own problem

Type it, or draw it with your mouse or finger. Equations, derivatives, matrices, triangles, primes — or a word problem the tutor breaks into parts.

What each stage covers

Hər bir əsərdə bir-birindən fərqli, lakin bir-birinə yaxın olan, bir-birini tamamlayan və bir-birini tamamlayan elementlər vardır.

Stage 1 Arithmetic Numbers, fractions, percentages and the order of operations. Stage 2 Algebra Equations, inequalities, factoring, functions and systems. Stage 3 Geometry Triangles, circles, polygons, solids and coordinates. Stage 4 Trigonometry Angles, the unit circle, identities and trig equations. Stage 5 Precalculus Functions in depth, complex numbers, sequences, conics and vectors. Stage 6 Calculus Limits, derivatives, integrals, series and optimisation. Stage 7 Linear Algebra Matrices, determinants, inverses, row reduction and eigenvalues. Stage 8 Statistics & Probability Averages, spread, counting and probability. Stage 9 Discrete Math & Logic Counting, logic, truth tables, sets and proof. Stage 10 Number Theory Primes, divisibility, gcd, modular arithmetic and sequences. Stage 11 Differential Equations Equations whose unknown is a function: growth, oscillation, and how physics is written. Stage 12 Analysis Limits made rigorous: sequences, series, convergence, improper integrals, complex numbers as functions. Stage 13 Frontiers The open problems — Riemann, Navier–Stokes, P vs NP — broken into what you need to even read them.

Bu necə işləyir

1

Type it or draw it

“derivative of x² sin x”, “is 561 prime”, “triangle 3 4 5” — or sketch the equation on the pad and it is read for you.

2

Hər hərəkəti izlə

Bir qayda hər addım üçün — məhsul qaydası, bir sıra əməliyyatı, Euclid bölməsi — animasiya edilmiş və cümlədə izah edilmişdir.

3

Onun şəklini gör

Əsası qeyd olunmuş eğrilər, dönə bilən səthlər, ölçüyə uyğun üçbucaqlar, faktor ağacları, məkandakı vektorlar kimi matrisə.

Mümkün olmayanlar da

A word problem, a proof, an open question: the tutor breaks it into parts you can attack, tells you what is known, and hides the solution until you want it.
