The problem of managing the reserve of cobalt is presented, followed by a method for bringing the stockpiled amount from any level to a desired goal. Solving a stochastic programming problem is involved. The procedure is discussed in detail. (MNS)

Two computer programs are given to provide simulations, for any value of n, to keep count of the frequency of the first significant digit. (MNS)

How min-max problems can be solved with trigonometry and without calculus is described. (MNS)

Relationships between mathematical and humanistic cultures and the development of mathematical concepts are presented. The author suggests that courses highlighting the history and relevance of mathematics be developed; possible instructional resources are listed. (SD)

Six mathematics problems are posed; details are given of the solutions for six other problems. (DT)

Instructions are given for making a flexagon; the possible transformations of the flexagon by flexing and turning are shown to form a non-abelian group of order 6. (DT)

The problem of determining the number of squares on a checkerboard is extended to finding the number of rectangles on an n x n board and finding the total numbers of cubes and rectangular solids in an n x n x n cube. (DT)

The aims of this project, which is developing a new Advanced Level course for use in English schools, are illustrated by examples of their textual materials. (MM)

Notes on De Morgan's rules; a perpetual calendar; the use of coloured rods; a balance problem; a graphical approach to natural logarithms; a problem in geometric probability; and the parallelogram law of forces. (MM)

The predicted and actual achievement in college calculus is compared for students who had studied two semesters of calculus in high school. The regression equation used for prediction was calculated from the performance data of similar students who had not had high school calculus. (CT)

Forty-eight mathematicians in industry, business, and government replied to a questionnaire on the relative merits of the traditional undergraduate curriculum, advanced topics in pure mathematics, computer programing, additional computer science, and specialized or applied topics. They favored programing and applied mathematics, along with a…

Developed are simple recursion formulas for generating the exact distribution of the longest run of heads, both for a fair coin and for a biased coin. Discusses the applications of runs-related phenomena such as molecular biology, Markov chains, geometric variables, and random variables. (YP)

Offers an approach to the understanding and to the teaching of the fundamental theorem of calculus. Stresses teaching the relation between a function and its derivative and the functions themselves. (YP)
