#### Vector representation of multiplication and division of complex numbers

(National Council of Teachers of Mathematics, 1954-05)

One question raised by students in mathematics is how to represent multiplication and division of complex numbers by vectors in rectangular co-ordinates. The purpose of this brief paper is to present a simple explanation ...

#### Involution operated geometrically

(National Council of Teachers of Mathematics, 1955-04)

High school students of plane geometry may be interested in the central theme of this paper as a generalization of the usual problem of finding a line equal to the square of a given line.

#### Mathematical miscellanea: Two cube root curves

(National Council of Teachers of Mathematics, 1955-12)

It is a matter of common knowledge that it is impossible to duplicate a cube by means of the straightedge and compasses. There are, however, several methods which make use of algebraic curves. This presentation is intended ...

#### Squaring a circle

(National Council of Teachers of Mathematics, 1957-01)

It is impossible to construct a square equal to a given circle by the exclusive use of a straight edge and compass. This paper is intended to present a solution to this problem with a slight departure from the purely ...
