... Let S be a subset of the real numbers (for instance, we can choose S to be the set of natural numbers). If f and g are functions from S to the real numbers, then we write g  (f) if and only if there exists some real number n0 and positive real constants C and C’ such that C|f(n)|<= |g(n)| <= C’|f( ...

... We label these points on the number line using an open circle for x = 3 since this is not in the domain, and a closed circle for x = 4. The critical points divide (partition is a nice word) the number line into three sections. Numbers less than x = 3 work in the inequality, as do numbers greater t ...

Elementary mathematics



Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
