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

हर व्यक्‍ति एक ऐसे जीवन - शैली, दृश्‍य, और उसके लिए एक वाद - विषय का एक नमूना है ।

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.

कैसे यह काम करता है

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

हर चाल देखें

एक नियम है, उत्पाद नियम, एक पंक्ति प्रक्रिया, एक यूपीपिड विभाजन — सजीव और वाक्य में समझाया ।

3

इसका आकार देखिए

उनकी जड़ें चिह्नित, सतह के साथ वक्र आप घुमा सकते हैं, त्रिकोण के स्केल, फ़ैक्टर पेड़, अंतरिक्ष में सदिश के रूप में स्केल करने के लिए बनाया गया है.

4

असंभव जन भी

एक शब्द, एक खुला सवाल, एक खुला सवाल: शिक्षक इसे आप पर हमला कर सकता है, आपको बताता है कि क्या ज्ञात है, और जब तक आप इसे चाहते हैं, हल छिपा देता है.
