(Software engineers don't count). Real life examples would be great.

I use more Linear Algebra than anything.

Someone once told me of someone who once did but I doubt if it's true..

Yes. In fact, many do. In Aerospace, you need calc to figure stress from things such as cantilever wings and such. However, the formulas are sometimes already known and so it might not appear to be calc.

I use it all the time when calculating shear and moment diagrams.

Yes, mostly integrals and derivatives. These are usually computed numerically.

I needed it once to calculate the rolling moment of inertia of a paper roll going down a ramp off a winder.Had a graph for water usage, needed numerical integration to get the total volume of water for the day from the graph.

So often you don't even think about it.Admittedly, most of it is pretty simple stuff for the aforementioned shear, moment, deflections, etc.Every now and then I even break out the DiffEQ!

I have been an EE for 10 years and can't think of a time when I ever used it. Like a previous poster, I use linear algebra quite a bit, as well as some trig functions in equations.

The principle of calculus is used to compute earthwork quantities. For open channel flow, calculus principles are used to compute flow profiles.
