Hence, only the dark dots refer to finite definite values. The left-hand side endpoint is a dark dot in order to show that the point is part of the graph while the right-hand side endpoint is an arrow denoting that the values are infinite. The graph gives a picture of a group of steps and so it is known as a Step Function Graph. This phenomenon can be explained by the thermal expansion of the. However, if the permeability is K3×10 20 m 2, the hoop stress is not a monotonic function and can become tensile for some period of time during the deformation. X 1 means the value of x can be x= 1, 2, 3, 4, 5…īy plotting the above values on graph paper, the following graph can be obtained. The hoop stress is a monotonic function of time and entirely compressive if the permeability is K3×10 19 m 2.
This book also has instructions about how to use COMSOL Multiphysics and how to access the electronic Documentation and Help content. Solution: From the given data we have, -2, 0, 2 are the respective values of y. The COMSOL Multiphysics Reference Manual describes the core physics interfaces and functionality included with the COMSOL Multiphysics license. A step function f: R → R can be written in the form: For example, it can be used to coordinate all the steps of a checkout process on an e-commerce site. The step function is used to coordinate session-based applications. Students may come across the step functions while learning other types of functions, for example, sign function “sgn(x)”, Heaviside Function, and Rectangular function, etc.
A step function is also known as the Greatest Integer Function or Floor Function. A step function is explained as a finite linear combination of indicator functions for given intervals.
