Two traditional presentations introducing the calculus of exponential functions are first presented. Then the suggested direct presentation using calculators is described. (MNS)

Introduces a proof of Sarkovskii's Theorem based on the intermediate value theorem, making it accessible to readers with knowledge of calculus. The theorem deals with k-period continuous functions, functions for which fk(x)=x, where fk(x) is the composition of the f function k times. (MDH)

Plotting a polynomial over the range of real numbers when its derivative contains complex roots is discussed. The polynomials are graphed by calculating the minimums, maximums, and zeros of the function. (MNS)
