The Third UN Law of the Sea Conference are well-known and Laplace transform techniques can be readily applied to obtain both natural and forced responses. Consequently a large proportion of all physical systems, including a majority of electrical network configurations, can be adequately described mathematically. However when the constr

The General Assembly Reconsidered they are generally of little value in most applications, especially when many solutions are required. There are, however, a few specific types of periodic equation that can be solved analytically and for which the solutions appear in an easily used form. So useful and simple in fact are these sp

Power Politics and the United Nationsmmonly encountered Hill equation—viz. the Mathieu equation—belongs in that class. In practice therefore physical descriptions are sometimes compromised to render the equation solvable, or else only approximate solutions to the equations are sought. Clearly, in each case, essential information may be
