FC-Win 5.12.5

FC-Win (tm) is a front-end program for FortranCalculus (tm). The FortranCalculus (FC) language is for math modeling, simulation, and optimization. FC is based on Automatic Differentiation that simplifies computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition. Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand. 60+ examples

Match n Freq 5.12.5

Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Another improved productivity example do to using Calculus (level) programming.

Robot4 0.73

Robot4 (tm) is a Robotic Arm Movement program where the arm is moved from a given position to a desired position. The program finds the angles necessary for the desired position. Problem came from NASA.Robot4 is an Inverse Problem example. It wants to solve how to move from starting point 'A' to target 'B'. An improved productivity example do to using Calculus programming. See 'Rob4User.fc' file.

Quantum Hulls 1.0

Visualization of the polyhedra whose vertices have repelled eachother on the surface of a sphere, until their positions have stabilized. The simplest such polyhedron has 4 vertices, and naturally becomes a tetrahedron. The remaining polyhedra, with an integral number of vertices, are NOT regular polyhedra. I call them "quantum hulls" because they are all convex hulls with triangular faces, and the number of vertices is quantized.

Factoring Calculator 1.0

Factoring Calculator is a software for number conversion programmed to calculate the number of prime factors for a given number. In mathematics, factorization or factoring is the decomposition of a number into a product of other objects, or factors, which when multiplied together give the original.

LCM Calculator 1.0

The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Denominator (LCD). For 2 integers a and b, denoted LCM(a,b), it is the smallest integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30. For the least common multiple of more than 2 numbers, say a, b, c and d, it is the smallest integer that is evenly divisible by all numbers.

Standard Deviation Calculator 1.0

Standard deviation is a widely used measurement of variability or diversity used in statistics and probability theory. It shows how precise your data is. The standard deviation is the square root of its variance. A low standard deviation indicates that the data points tend to be very close to the mean, whereas high standard deviation indicates that the data are spread out over a large range of values.

Gigra Cool Math Game 1.0

Our Cool Math Game is quite simple. You set time and try to solve as many problems as you can. Enter number of seconds you would like to have for a game session. Then click start and give answers to the problems you see. You will be given one point for every correct answer you give.

Gigra Area Converter 1.0

If you already know, area can be calculated by multiplying length by width. To make things easier, we created this free tool that converts instantly between acres, square feet, square miles and other units. Enter the value, select the unit and then select the unit you want to convert into. Then simply click on double arrow to get the result.

Gigra Distance Calculator 1.0

You can calculate time from distance and speed, distance from speed and time, and speed from distance and time with this simple piece of software. Enter the values in required fields and get the answers you were looking for. Fast and easy. Simple interface.

Fraction Calculator 1.2

Fraction Calculator name speaks for itself. This piece of software will help you to add, subtract, multiply and divide fractions. Enter fraction #1 and fraction #2. Make sure you use / between numerator and denominator (e.g. 1/3 for one third). Select what operation you want to perform and click Calculate Fraction button to see result.

GPA Calculator 1.2

This GPA Calculator lets you determine how your current term will affect your overall GPA. You can use it before you know your grades to predict your CGPA (Cumulative Grade Point Average). Due to the way this calculator is made, it won't calculate grade replacement if you are repeating a course. GPA Calculator will include both failing and new grades.

Roman Numeral Converter 1.1

This tool lets you converter roman numerals to traditional numbers, and traditional numbers to roman numerals. A smaller number in front of a larger number means subtraction, all else means addition. For example, IV means 4, VI means 6.You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3.

Quadratic Equation Solver 1.1

Quadratic equation has the form ax2 + bx + c = 0. It will generally have two solutions; that is, two different values of x that make the equation true. It can happen that both solutions are the same number, and it is possible that the solutions will be complex or imaginary numbers. To use this software, type in values for a, b, and c in the boxes below, and press the Solve for X button.
