1. (1) integer number (2) constant (3) higher mathematics
(4) inequality (5) function (6) formula
2. (1) From the early need of man came the concepts of numbers and forms. Then,
geometry (几何) developed out of problems of measuring land, and trigonometry
came from problem of surveying. To deal with some more complex practical
problem, man established and then solved equation with unknown numbers, thus
algebra occurred. Before 17th century, man confined himself to the elementary
mathematics, i.e., geometry, trigonometry and algebra, in which only the constants
were considered.
(2) A large variety of scientific problems arise in which one tries to determine
something from its rate of change. For example, we could try to compute the
position of a moving particle from a knowledge of its velocity or acceleration. Or a
radioactive（放射性的）substance may be disintegrating at a known rate and we
may be required to determine the amount of material present after a given time. In
examples like these, we are trying to determine an unknown function from
prescribed in formation expressed in the form of an equation involving at least one
of the derivatives of the unknown function.
