That time you asked when will differential calculus and limits come in handy in real life?

In high school all I did was the minimum, metal shop,and auto mechanics. No haircut for the coach. Later I went to college and did Algebra, College Algebra, Trigonometry. Still later on while I was restoring British cars a buddy kept bugging me to be a draftsman. First week I was a designer. All that, all that simple math in college began to click. After a while I had enough time working under a licensed engineer to take a test in Texas to become a licensed engineer. I knew I would have to learn Calculus. My wife's company moved us to Austin TX. Instead, I began playing Bass in bands.

We had two Questions of the Day that addressed piston velocity/cylinder volume using algebra and trig:
Initially using Differential and Integral equations with Boundary conditions often results in simplified equations using algebra and trig.
Piston Velocity and Position
For this two-part problem we're going to use my 4.3L Vortec V6 in this example. Data: The engine's crankshaft is rotating at 1000 RPM. The Piston Stroke is 3.48 inches. To simplify the problem somewhat, neglect any connecting rod angles (for now). The usual Piston Stroke Length Ls and crank...

Volume Verses Crank Angle
In this Question we will continue to use my 1999 S-10 engine (6-cylinder, 4.3L Vortec) as the question Example. Data: The total Displacement of the engine is 262.3 cubic inches. Bore is 4.012 inches, Stroke is 3.48 inches, and the Connecting Rod Length is 5.7 inches from center of Wrist-Pin...

I got a D- in college calculus and was darn happy to get it. after getting a B In algebra in that completed my 12 hrs of math requirement. Was unable to sell my calc textbook at price I wanted, so i kept it. This was way back in 1978 at North Dakota State. some 40 years later I found a use for my huge calculus book as a doorstop. Took over 40 years but I did finally use calculus or at least the book
Dwell time. When you are figuring compression ratios with liquid and a plastic cover there is always a degree or two of crankshaft movement at tdc available that doesn't move the oil around at all. Some may be bearing clearances but I doubt it. If it has no effect than does it matter? I'm sure the math is going to make me eat my words but I don't care.
I used to have an automotive math book ,,when I moved I gave it away that had the formulas for pretty much everything Automotive. Plug in the numbers and do the math. If the answer didn't seem correct ask a smarter friend.
