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
각각의 레슨은 실제로 작동하는 예제, 시각적 효과, 그리고 그에 맞춰 튜닝된 솔버가 있는 레슨 세트입니다.
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.
어떻게 작동하는지
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
모든 움직임을 지켜보세요
단계당 하나의 규칙 - 적분 규칙, 행 연산, 유클리드 분할 - 애니메이션, 문장에서 설명.
3
그것의 형태를 보십시오
루트가 표시된 커브, 회전할 수 있는 표면, 크기에 따라 그려진 삼각형, 요인 트리, 공간에서 벡터로서의 매트릭스.
4
불가능한 것들도
단어 문제, 증명, 개방형 질문: 튜터는 공격할 수있는 부분으로 분해, 알려진 것을 말해, 당신이 원할 때까지 솔루션을 숨깁니다.
