On the Behavior of y Equals x to the n Power Times Sin 1/x.
Peer reviewed Peer reviewed
Webster, Porter G. – Mathematics and Computer Education, 1985
The behavior of some functions near the point of origin is discussed. Each function oscillates, and as x approaches 0, the oscillations become increasingly more rapid; their behavior near the origin improves with increasing values of n. Examples for a calculus class to consider are given. (MNS)

Infinite Series and Improper Integrals: A Dual Approach.
Peer reviewed Peer reviewed
Fay, Temple H.; Webster, Porter G. – Mathematics and Computer Education, 1985
Provides examples to show that parallel coverage of convergence theorems for both series and improper integrals will tend to strengthen each other. Indicates that such coverage should also help students to better understand the concept of asymptote. (JN)
