It is very well known that the Cauchy-Schwarz inequality is an important property shared by all inner product spaces and the inner product induces a norm on the space. A proof of the Cauchy-Schwarz inequality for real inner product spaces exists, which does not employ the homogeneous property of the inner product. However, it is shown that a real…

A problem, motivated by the conversion of Fahrenheit to Celsius, is related to classical Diophantine equations. (MK)

Explains the significance of the mole as a unit of measure by showing the relationship between physical quantities and their mathematical representations. Offers a summary of the principles of metrology that make creation of physical quantities and units seem reasonable. A table of base physical quantities and units is included. (RT)

Written for remedial/developmental students without algebraic skills, these three arithmetic modules for electronics cover measure, formulas, and pythagorean theorem. The self-paced modules incorporate use of calculators. With this aid the level of difficulty of comprehension is approximately seventh grade. Module 1, Measure, covers nine topics:…

This section includes brief articles on holding a 'metric review show,' the 'normal' approach to graphing, graphing polynomials by using the powers of the factors, and some sum derivations. (MNS)

Proposes a method for dealing with units that require involvement of units of each physical quantity at every stage of a calculation. Preliminary ideas on algebra and the concept of a physical quantity, equations relating two or more units, calculations of physical quantities, and logarithms are considered. (JM)

A project was undertaken to develop a remedial academic curriculum and materials that would help disadvantaged students gain the basic mathematics skills necessary to succeed in an electronics program. Major activities of the project included development of a bibliography of currently available math resource books with materials appropriate for…
