Unformatted text preview: • The program should be executed on obtained or computed test data for which the answer or solution is either known or which can be obtained by independent means, such as hand or calculator computation. • Intermediate values should be compared with expected results and estimated variations. When values deviate from expected results more than was estimated, the source of the devi ation should be determined and the program modified as needed. • A “reality check” should be performed on the solution to determine if it makes sense. • The assumptions made in creating the mathematical model of the problem should be checked against the solution. 1.2 Problem Solving Example As an example of the problem solving process, consider the following problem: A small object is launched into ﬂight from the ground at a speed of 50 miles/hour at 30 degrees above the horizontal over level ground. Determine the time of ﬂight and the distance traveled when the ball returns to the ground....
