Several problems that can be encountered with displaying numerical data are discussed, with particular view to some of the limitations on the Apple II computer. A subroutine in BASIC is listed which solves all of the problems for users who can use a scientific notation format. (MP)

This document explains A Programming Language (APL) and describes the experiment that the Information Processing Division has undertaken to introduce APL to the Goddard Scientific Community. A brief historical sketch of steps taken to date is included and appendices giving illustrative examples of how APL actually has been used at the Goddard…

Useful programming tricks are suggested to allow the reduction of many equations and non-polynomial-like expressions and the subsequent application of the mathematical algorithms. (Author)

Examines the similarities and fundamental differences between procedural programing and logic programing by comparing LogoWriter and PROLOG. Suggests that PROLOG may be a good first programing language for students to learn. (MVL)

Some of the important concepts in recursive programing are detailed, along with how they can be used. Examples are provided to show how to program recursively in BASIC. (MP)

A mathematical technique for solving for the interest rate of a given annuity is explained. The technique is applied to a BASIC program that finds interest rate given the future value, number of payments, and the value of the payment. (MP)

Mathematical programing formulas are introduced as new approaches to solve the classification problem in discriminant analysis. The research literature is reviewed, and an illustration using a real-world classification problem is provided. Issues relevant to potential uses of these formulations are discussed. (TJH)

A program written for the 16K Level II TRS-80 computer that prints a star map, using various mathematical formulas to compute positions of the stars and the moon and displays them on terminals, is discussed. Some relevant astronomical background and terminology are covered in order to aid understanding. (MP)

A sample mathematical application problem that can be solved with computer programing is discussed. (MP)

Developed and demonstrated here is the design of interface systems for cost-effective communication of the user with the computerized operations research procedures. The concentration is in the area of interfacing methods for implementing the optimization techniques of mathematical programing. Emphasis is given to flexibility of accessing the…

A computer simulation of the Buffon Needle Problem for estimating the value of pi is discussed. (MP)

Presents a ray-tracing procedure based on some ideas of Herzberger and the matrix approach to geometrical optics. This method, which can be implemented on a programmable pocket calculator, applies to any conic surface, including paraboloids, spheres, and planes. (Author/GA)

A PROGRAM THAT WOULD DEVISE OPTIMAL ROUTES FOR SCHOOL BUSES WAS DEVELOPED. ONE OF THE TWO MODELS DEVELOPED FOR THIS STUDY, CALLED THE HEURISTIC MODEL, WAS A HAND PROCEDURE BASED ON THE ASSUMPTION THAT, IN AN EFFICIENT SCHOOL BUS SYSTEM, STUDENT MILES SHOULD BE MINIMIZED RATHER THAN BUS MILES. THE OTHER MODEL WAS DESIGNED TO BE USED WITH HIGH SPEED…

Develops a general computer algorithm to obtain a magic square having a number of rows that is a multiple of four. Presents a BASIC program and sample runs. (YP)

The authors provide a list of calculators which have a capacity for handling programs, and a list of programs for such calculators which are available at cost. They argue that the use of these materials at many levels of mathematics instruction enhances both motivation and understanding. (SD)
