Chapter 14, Problem 14.5E

Explanation of Solution

Protection of data with the use of defensive layers:

Systems with more defensive layers are more secure and if these layers work independently then better results can be derived. The defensive layers which are included in any information system for maintaining better security of data items are mentioned below:

  • User authentication:
  • This layer is used to check that the particular user is authorized to access the desired data or not. Information system will be able to maintain system generated user ID and instantly generated password for security of data items...

Write a C program to calculate the function sin(x) or cos(x) using a Taylor series expansion around the point 0. In other words, you will program the sine or cosine function yourself, without using any existing solution. You can enter the angles in degrees or radians. The program must work for any input, e.g. -4500° or +8649°. The function will have two arguments: float sinus(float radians, float epsilon); For your own implementation, use one of the following relations (you only need to program either sine or cosine, you don't need both): Tip 1:  Of course, you cannot calculate the sum of an infinite series indefinitely. You can see (if not, look in the program) that the terms keep getting smaller, so there will definitely be a situation where adding another term will not change the result in any way (see problem 1.3 – machine epsilon). However, you can end the calculation even earlier – when the result changes by less than epsilon (a pre-specified, sufficiently small number, e.g.…
