Question

2. There are two primary methods of building up a solution to an engineering model, 1) analytical, and 2) numerical. Provide a description of each of these methods, explaining in detail what they are being employed for, when they would be employed, and why a given method would be employed rather than the other. answer should be relavent to engineering system unit please.

Answer 1

Ans : There are two methods for solving problems in an engineering model which are mentioned below :

ANALYTICAL METHOD :

1. This method provides us with an exact solution to a problem or equation .
2. It involves a set of pre-defined steps . Where Step 2 is very important .
3. It includes surrounding the issue in a know structure which would helps in figuring out the specific arrangement or the solution to that problem .
4. These problems won`t require any use of computer service they can be solved with the help of pen and paper .
   

NUMERICAL METHOD :

1. It gives us an estimates that are very close to exact solution .
2. They are very time consuming because results can`t be obtained exactly in finite time .  
3. It requires testing again and again which would require error and trial method for the solution and the testing would modifiy the results well so as to get as close to the accurate result .
4. These problems requires the help from computer as they can't be solved with pen and paper but can be solved with the help of C++ .

Utilization of Analytical Method : Utilize of the Explanatory Method is key in taking care of the common sense issue since unmistakably current method are inadequate. they're instinctual, clear, and subordinate on how activists approach standard issues. Consequently they're liked by the analyst for their consistent computations .

Utilization of Numerical Method : They utilizes the mistakes and preliminary technique which are slow when compared different investigative strategies and during this way they furnish us approximate outcomes but not the accurate ones .In recent times the numerical methodology are used which is a good deal of issues don't appear to be systematically reasonable and that we realize they add light of the very fact that every different procedure comes bundled with an indication that it works. It's works very quick thanks to its settling from reasonable to unsolvable issues

Method used or preferred the most is ANALYTICAL : Because of numerous reasons that this strategies provides foremost accurate and meaningful answers. Therefore we have a condition indicating us precisely what occurs with every factor. Numerical strategies are typically progressively adaptable in what problems they will solve.The difference between them are listed above
