### What's New

The update provides a complete overhaul of the mathematical explanations and definitions, which greatly enhances the learning experience of the students. It enables them to understand every concept and notion, that was formerly too difficult to grasp.
MATH 42 2.2 is 10x - 100x faster compared to previous versions, which makes MATH 42 even snappier than before.

### App Description

MATH 42 helps middle-school-, high-school- and college-students to understand mathematics better. It helps them with homework, ahead of tests and during studies with (1) intelligent approaches to the solution, (2) Step-by-Step solutions and (3) a training- and test-mode. Exercises and solutions can be posted on Facebook and sent by eMail.

FREE MATHEMATICAL FEATURES

All math that was free up until now will also be available for free in this version of MATH 42.

• Simplifications and transformations (Signs, combining, factorizing, binomial decomposition, …)
• Fractions (adding, reducing, multiplying, simplifying, GCD, LCM, …)
• Logarithms and trigonometric functions (rad/deg)

• Linear equations
• Fractional equations
• Systems of equations (linear and non-linear)

• Polynomial long division

• Derivation (sums, exponents, products, quotients, chain, powers, roots, trigonometry, …)

• Graphical Curve Sketching (Derivation, roots, extremes, inflection points, poles, asymptotical functions, intersection points)

The Premium features are available for registered users for free for one month. From there on they’ll be available through a subscription.

• Equations of higher degree (numerical solutions, substitution)
• Exponential, logarithmic and trigonometric equations (Substitution)
• Absolute value and inequations (Case distinction)

• Polynomials (Roots, factors)

• Integrals (By parts, by substitution, partial fraction decomposition), definite and indefinite integral

• Curve Sketching (Derivation, roots, extremes, inflection points)

• Matrices (adding, multiplying, determinant (2x2, Sarrus, Laplace), inverse, characteristic polynomial, eigenvalues and -vectors, kernel, rank, Gauss-algorithm, LSE)

SUBSCRIPTION OPTIONS

• 1 month for 8,99 USD
