History of Calculus - Symbolic Methods

Symbolic Methods

Symbolic methods may be traced back to Taylor, and the much debated analogy between successive differentiation and ordinary exponentials had been observed by numerous writers before the nineteenth century. Arbogast (1800) was the first, however, to separate the symbol of operation from that of quantity in a differential equation. François (1812) and Servois (1814) seem to have been the first to give correct rules on the subject. Hargreave (1848) applied these methods in his memoir on differential equations, and Boole freely employed them. Grassmann and Hermann Hankel made great use of the theory, the former in studying equations, the latter in his theory of complex numbers.

Famous quotes containing the words symbolic and/or methods:

    The symbolic view of things is a consequence of long absorption in images. Is sign language the real language of Paradise?
    Hugo Ball (1886–1927)

    Parents ought, through their own behavior and the values by which they live, to provide direction for their children. But they need to rid themselves of the idea that there are surefire methods which, when well applied, will produce certain predictable results. Whatever we do with and for our children ought to flow from our understanding of and our feelings for the particular situation and the relation we wish to exist between us and our child.
    Bruno Bettelheim (20th century)
