Presents a biography of the theologian and philosopher, Francis William Newman (1805-1897), the brother of John Henry Newman. His mathematical contributions were primarily in the area of analysis. (RS)

The author suggests that a close analysis of existing calculus courses indicates that some of the material can be explained much more clearly by using some of the language of set theory. He gives examples showing that many of the pedagogical problems arising in calculus can be overcome by using a graphical approach. (FL)

A program that can reduce difficult integration problems to simpler approximations using the trapezoidal rule to approximate the area under a curve is presented. (MP)

The notion that the area of an inscribed n-sided polygon approaches the area of a circle as n approaches infinity leads to some interesting limits involving trigonometric functions. (MP)

Two problems related to the mean-value theorem lead into a problem requiring the use of the universal chord theorem. This latter theorem is discussed and a proof given. (MP)

An identity for sin x/x is proved. Rate of convergence, a geometric interpretation, and an application from physics are discussed. (DT)

Data from 99 students who completed a microeconomics course indicated that better grades in calculus led to significantly better grades in microeconomics. Higher levels of prior achievement as shown by grade point average correlated with better microeconomics performance. (SK)

Presents examples of using a tic-tac-toe format to practice finding the slope and identifying parallel and perpendicular lines from various equation formats. Reports the successful use of this format as a review in both precalculus and calculus classes before students work with applications of analytic geometry. (JRH)

Documents the experiences of 25 first-year university students with regard to the kinds of tasks calculus instructors should design in order to engage students in mathematical practices that often require the use of a graphing calculator. (MM)
