Hi guys!

I'm here again with a general question that's been bothering me all day today as I study for my calc 2 exam which is primarily on tests:

I'm taking Calculus 2 for Physics/Engineers as part of my course curriculum for getting a Bachelors in Chemistry and I'm doing well in understanding the tests and applying them solely in a mathematics reference frame but...

What are the real life applications of these tests? I like to understand why I'm doing what I'm doing so I figured I'd ask this community. How will these tests help me in my future endeavors as a chemist/engineer/programmer?
