Another Look at Real-World Problem Solve 1.0

In our paper, A LOOK AT REAL-WORLD PROBLEM SOLVING, a projectile trajectory problem was studied. In that paper, a closed-form expression (an exact equation) to the trajectory problem (required angle to reach a point) was found. Closed-form solutions are rarely possible in the real-world. We usually resort to solving our problems numerically, using a computer. In this work (ANOTHER LOOK AT REAL-WORLD PROBLEM SOLVING), we look again at the projectile problem, but the solution emphasis is on iterative, numerical solutions. Both one-dimensional and two-dimensional solution methods are discussed, as are some of the checks that must be made and the pitfalls that should be avoided when using such methods. For classroom purposes, examples of potential applications of the trajectory equations are discussed.
