Question
Chapter 11, Problem 56E
Program Plan Intro
Disk scheduling:
- In a computer, multiple processes run over the same time.
- To handle this multiple processes, the
operating system decides which process has to be executed first. This technique is called as disk scheduling. - There are different types of scheduling algorithms. They are as follows:
- First-come, First-served (FCFS)
- Shortest-Seek-Time-First (SSTF)
- SCAN
SCAN disk scheduling
- The SCAN algorithm is called as elevator algorithm.
- In the SCAN algorithm, the disk arm starts at one end of the disk and moves toward the other end.
- It processes the request for each cylinder until it gets to the other end of the disk.
- At the other end, it reverses the direction of head movement.
- The head continuously moves back and forth across the disk based upon the closest distance.

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.…arrow_forward
