<p>One way to view any branch of engineering is that an engineer describes physical (or chemical) systems mathematically, tests those models against known results and then uses those math models to predict responses against new set of conditions. Of course, most of these math models have already been developed, tested and verified over the years. But you never know where your work will take you. You may have to put those math skills to use.</p>
<p>Most math models involve some kind of differential equation as this world is hardly ever static (even in “statics”). However, trying figure out which 10% of what you learned you will actually use is difficult. You might go to something like MIT’s OpenCourseWare to see how the math is used in various subjects like statics, dynamics, heat transfer, etc. You should have figured out the WHY the math works in your classes as that is the critical part of your math education and the part that is used in engineering.</p>
