MATH 423.3.24

MATH 42 helps over 2.200.000 middle-school, high-school and college students, to solve their math problems and get better grades at the fraction of the cost of a private tutor. MATH 42 helps with (1) intelligent approaches to the solution, (2) step-by-step solutions of their problems (3) an Assessment Center. MATH 42 is a trusted mathematical resource around the world and the numbers prove it: Over 2.2 million downloads, used on over 450.000 tablets in schools, in cooperation with the biggest educational publisher in Germany (lett). FEATURES Intuitive entry of formulas Intelligent suggestions on how to approach a problem (unique worldwide) Detailed step-by-step solutions, that adapt to a students need (unique worldwide) Extensive corresponding mathematical explanations with examples Interactive graphs, that visualize problems Automatically generated and curated assessment, that enables and facilitates rapid progress Instant-Calculator, that computes during the entry ASSESSMENT CENTER Exercises subdivided by topic and level Training mode - afterwards, each problem can be analyzed step-by-step Test mode - enabling the identification of strengths and weaknesses Test results and statistics show progress over time Tests and exercises were created in cooperation with experienced pedagogues and private tutors MATHEMATICAL FEATURES Term Transformation Simplyfing and expanding Factorization (Factoring out, application of the binomial formulas) Transforming powers and roots Adding fractions, multiplying fractions, reducing fractions, expanding fractions Computing the gcd and the lcm Trigonometric transformations (Is being enhanced) Logarithmic transformations (Is being enhanced) Functions Roots Y-axis intersection Domain of definition Extremes (Maximums, Minimums) Inflexion points Curve sketching Derivation Fundamental derivatives, Factor rule Sum rule Product rule Quotient rule Chain rule Integration Fundamental integrals, Integration by substitution Integration by parts Partial fraction decomposition Equations Linear equations Quadratic equations (Completing the square, quadratic formula, pq-formula) Special equations of higher degree Linear systems of equations Non-linear system of equations Matrices Adding matrices Multiplying matrices Transposing matrices Inverting matrices Determinants Characteristic polynomials Eigenvalues Eigenspaces ernels Ranks Cross-product Gaussian elimination TECHNOLOGY MATH 42 works without templates or pre-calculated solutions MATH 42 solves all problems on the fly, like a teacher at the board MATH 42 is a real symbolic algebra system MATH 42 bases on artificial intelligence MATH 42 is a completely self-developed system
