CombiStatX calculates statistical mean & standard error deviation.
ComplexMatrix Plugin adds complex matrices to the functionality of my Complex and Matrix plugins. If you are using those plugins you should remove them.
Eigenmath is a free symbolic calculator that is simple to use.
Fraction Plugin for REALbasic 5.5.5 and later allows you to construct programs which can handle fractions much like doubles and integers are handled. A fraction is represented by two integers, num/den.
FractionAction X is for converting Rational Numbers (within limits) in base 10 between fraction, decimal & simple continued-fraction representation.
lets you add, subtract, multiply, and divide large fractions without having to convert from decimal form
Geo-Calc is a geometry calculator. You can use it to work out all the measurements (area, perimeter, sides, angles, etc) of 2D and 3D shapes. The shapes include Ellipses, Rectangles, Triangles, Trapeziums, Parallelograms, Polygons, Prisms, Cylinders, Cones, Pyramids and Spheres.
Iterit allows the user to explore and analyze the behavior of custom set functions when recursively iterating through them. Featuring the ability to create time series of a function, as well as a logistic map, along with the ability to geometrically illustrate iterations, Iterit is a must have for every mathematician or engineer.
MathPad is a general purpose graphing scientific calculator for the Macintosh. It uses text worksheets rather than simulating buttons on a hand held calculator. This live scratchpad interface allows you to see and edit your entire calculation. Formulas can be entered directly and different values can be plugged in for easy "what if" calculating.
qombinatorics is a graphical user interface to combinatorics calculus. With it you can easily calculate permutations and combinations of objects, as well as binomial coefficients. The results can be employed in many fields of statistics and probability calculation, graph theory, and so on. The software can also be useful for amusing activities like card playing.
Quadratic calculates the answers to
the Quadratic formula. As an extra feature that relates to the quadratic equation, it allows you to calculate pH and pOH.
Qubiter is a free computer program pertaining to quantum computers (QC) and quantum Bayesian (QB) nets.
Structurix is a calculation program based on the principle of the
finite elements. It makes it possible to solve plane problems with elements: bars, beams and triangulars. ElemFin allows the calculation of:
Displacements of each nodes, reactions to the supports and stress in
(commercial) a general trigometric and math application that assists in general trig, linear equations, matrices and more. Contains a QuickCalc and Unit Convertor
VFGEN is a program that takes a specification of a vector field (in other words, a system of differential equations) and generates source code for a wide variety of ODE solvers and other numerical tools. In other words, it is a vector field file generator for differential equation solvers and other computational tools.
