How do you use calculus in your work?

To become an engineer you must take a lot of math classes. I was wondering what kind of applications do you use in your career that relate to calculus classes and the methods learned in those classes? Also, how does having a thorough understanding of calculus techniques benefit you in your field of work and on what occasions do you use those techniques? A lot of what is learned in calculus seems to be unnecessary in any field of work, including engineering, how do you use, for example, integrals and derivatives in what you must do as an engineer?

Hello friend. I  asked to myself  the same question as you, many years ago. Then I learned that studying calculus and mathematics (I studied, five courses of mathematics and four physical) allows you to prepare your attitude for the resolution of complex problems. In my view, it is a kind of prior training, as the athlete begins training with jogging or the singer performs exercises to prepare her voice.

Secondly, there is sometimes specific knowledge not offered at the university that you will need when you're at work.  You may need to get a book and learn it yourself.  Sometimes that knowledge is based on physics or math, and if you don't have a base it will prove difficult to handle and understand.

Finally, engineering has many branches.  So for example the area of maintenance is very operational and may not require math every day, but if you are working in academics and research you will probably need to use mathematics and physics regularly.  In this sense I think it is necessary and indispensable to academic training for engineering.

In closing, particularly in my work, I do quality measurements of electric energy. I use measurement equipment that analyzes electrical current waveforms and voltage.  The analysis uses computers and requires comprehensive and complex calculations.  Although I use the computers and don't generally calculate myself, as an engineer I must know the process. I also used calculus many years after graduation, during my graduate studies.

I hope I have been helpful to your concerns
