As shown in Figure 3, if the discriminant is positive, the graph touches the x-axis at two points; if zero, the graph touches at one point; and if negative, the graph does not touch the x-axis. It is also possible to dene the inverse functions cos1 x and tan1 x by restricting the domains of the functions cosx and tanx. This leads to the polar form = = ( + ) of a complex number, where r is the absolute value of z, and is The most common convention is to name inverse trigonometric functions using an arc- prefix: arcsin(x), arccos(x), arctan(x), etc. Thus, the graph of the function y = sin 1 x can be obtained from the graph of y = sin x by interchanging x and y axes.

The important properties of step functions are given below: The sum or product of two-step functions is also a step function. Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continuous functions).Objects studied in discrete mathematics include integers, graphs, and statements in logic. The difference b A K x is the vertical distance of the graph from the data points: To emphasize that the nature of the functions g i really is irrelevant, consider the following example.
