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.
- In
mechanical Engineering, technologists or students use AUTOCAD or CATIA platform to draw designs in the software. - In physics, the experiments are performed on online platform and applets which help to visualize the results without actually performing the experiment.
“No”, the modern word processors don’t eliminate the need to develop spelling skills. They aid in performing checks against inadvertent errors, but the intellect and knowledge obtained from reading and learning through books and novels helps one to grow mentally.
- “Yes”, the technology might remove the need to read someday as everything is getting automated and learning platforms are getting based on videos and image content.
- Most of the students rely on online learning through video content rather than going through books and analyzing the data and problems.

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.

- It would be better to use a heuristic, rather than an algorithm, to solve a problem: when there are an infinite number of possible solutions when it is necessary to produce an answer that is extremely precise when there are no time constraints for finding a solution to the problem when the problem involves mathematical calculationsarrow_forwardAfter an exhaustive list of all of the mathematical operations has been collected, the steps in that list should be organised in a methodical fashion.arrow_forwardMake two lists of applications of matrices, one for those that require jagged matrices and one for those that require rectangular matrices.

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. Write, Compile and Execute…arrow_forward
