Dynamic Initial Allocation awl

Two new procedures for manipulating multiple stacks which share sequential memory locations are discussed. The first is the dynamic initial allocation procedure in which each stack is allocated as its first element arrives rather than having every stack preallocated at the very beginning of the entire process. The second is the local reallocation procedure; in this scheme, when a stack overflow...

Elliptic really does have a connection with literal geometric ellipses, removed by a few steps. Integrals expressing arc length of ellipses are less elementary than integrals for inverse trigonometric functions, and were named elliptic because of this. Abel and Jacobi discovered in 1827 that the inverse functions are doubly periodic (explained below). This chain of events caused these functions...

In studying lines in the plane, when we needed to describe how a line was tilting, we used the notions of slope and angle of inclination. In space, we want a way to describe how a plane is tilting. We accomplish this by multiplying two vectors in the plane together to get a third vector perpendicular to the plane. The direction of this third vector tells us the “inclination” of the plane. The p...

OVERVIEW When a body (or object) travels through space, the equations and that give the body’s coordinates as functions of time serve as parametric equations for the body’s motion and path. With vector notation, we can condense these into a single equation that gives the body’s position as a vector function of time. For an object moving in the xy-plane, the component function h(t) is zero for a...
