Forgot how to multiply matrices? Well, this app can help. It is like a gigantic, well-organized reference card for all things math. Customize your personal reference material by adding your own notes and build up a personalized list of favorites.
Math Ref has an amazing amount of reference material. It has a very intuitive interface and a great display. Under each of the topic headings, there is a large list of operations, properties, rules, and even examples.
Each of the topics includes a concise set of notes and properties that can be used for quick reference.
- Linear algebra
- Series and sequences
- Table of integrals
- Vector calculus
- Differential equations
- Discrete math
- Probability and statistics
- Greek alphabet
- Prime numbers
- Point 2 solver (finds polar coordinate, midpoint, x-intercept, y-intercept, distance, slope, equation of the line passing through the points)
- Line 2 solver (finds slope of each lines, point of intersection, acute angle)
- Quadratic solver (find discriminant, all real and imaginary roots)
- Remainder finder
- Log solver
- Exponential solver
- Complex solver
- Triangle solver
- Circle solver
- Sagitta solver
- Angle converter (degrees, radians)
- Function solver
- Inverse solver
- Reference angle solver

- Unit converter (computer, angle, length, area, volume, mass, force, speed, energy, power, pressure, temperature, time, magnetic)
- Projectile motion solver
Each property or equation is accompanied by a short description and space for you to type your own notes.
Specific notes or personal favorites can be shared via e-mail or printer.
Have students create their own "cheat sheet" as a review of important material, whether or not they get to use it for an exam. Use the print or share options to compare with a partner.
This app would make a good reference tool in the classroom, or for an advanced math student.
Consider dedicating one device in your classroom to reference tools such as these.
