Explanation of Solution
Use of abstract tools in the technology:
- Abstraction refers to the distinction between the external properties of an entity and the details of the entity’s internal composition.
- Abstraction that allows us to ignore the internal details of a complex device such as a computer, automobile, or microwave oven and use it as a single, comprehensible unit.
- Computers, automobiles, and microwave ovens are constructed from components, each of which represents a level of abstraction at which the use of the component is isolated from the details of the component’s internal composition.
- At each level of abstraction, system is viewed in terms of components, called abstract tools, whose internal composition is ignored.
- Development of large software systems is accomplished in a modular fashion in which each module is used as an abstract tool in larger modules.
- Subjects such as electrical engineering use MATLAB software to draw graphs, conclusions and simulate circuits without the need to work on paper...

Investigate both the iterative and the recursive methods of problem resolution, and then compare and contrast the results of your research. When would you use iteration when recursion would be more appropriate, and when would you use recursion when iteration would be more appropriate? Your answer should be justified by giving examples that are different from those that are shown on the slides of the presentation.
Why do we often resort to using MATLAB to find a solution to issues that emerge in computational geometry?
When faced with a problem in computational geometry, why is MATLAB the program that is most often recommended to use?

- TASK 3 The Persian mathematician Al-Karaji (953-1029) computed the first description of Pascal's triangle given below. It was later repeated by the Persian poet-astronomer-mathematician Omar Khayyám (1048-1131); thus the triangle is also referred to as the Khayyam triangle in Iran. 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 15 10 10 5 1 1 6 15 20 15 6 1 1 7 21 35 35 21 7 1 The Pascal's triangle determines the coefficients which arise in binomial expressions. For example, consider the expansion (x + y)? = x² + 2xy + y = 1x³y® + 2x'y' + 1x®y?. The coefficients of the terms are in the third row of the triangle. As a general approach, In general, when x + y is raised to a positive integer power we have: (x + y)" = aox" + ax-ly + azx"-?y² + ... + an-1xy-1 + any", where the coefficients a; in this expansion are precisely the numbers on row (n+1) of Pascal's triangle. Each row of the triangle can be computed by adding the pairs of numbers in the previous row from left to right.
