Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

1. Problem 1: Find two non-zero roots of the equation
sin(z) - 2²+1/2 = 0
Explain how many decimal places you believe you have correct, and
how many steps of the bisection method it took. Try to get as many
correct digits as you can. Also include timing results for your calcula-
tions.
