I had 3 semesters of Calc, majored in biochem and microbiology. When I got my first job in business I fell in love with that and never looked back. I don’t recall using Calc in anything but knowing what it could be used for was useful. When I finally reached senior management I could go ask our engineering department to run some numbers for me. They could generate information that was useful to management even if they didn’t all completely understand how we generated it. More people need to understand what you can do with Calc than actually know how to do calculus if that makes any sense. I never liked calculus class but I loved the concept of what all you could do with it. How, when, and where do we teach that? I don’t know, but I’m satisfied that engineers know it and they are a useful asset just like the rest of your fellow employees, everybody has a part.
I did well in Calculus, but we were never told what you could do with it.
