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

Masing - masing merupakan satu set pelajaran dengan contoh nyata, visual, dan pelarut untuk itu.

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.

Cara kerjanya

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

Perhatikan setiap gerakan.

Satu aturan per langkah ltu aturan produk, operasi baris, divisi Euclid animasi, dan menjelaskan dalam kalimat.

3

Lihat bentuknya

Kurva dengan akar mereka ditandai, permukaan Anda dapat memutar, segitiga yang ditarik ke skala, pohon faktor, matriks sebagai vektor di ruang angkasa.

4

Yang mustahil juga

Sebuah masalah kata, bukti, pertanyaan terbuka: tutor memecahnya menjadi bagian-bagian yang dapat Anda serang, memberitahu Anda apa yang diketahui, dan menyembunyikan solusi sampai Anda menginginkannya.
