Yeah, I've often needed tangents and cosigns, and of course who could go through life not knowing that all encompassing X+2Y(10)=30Y?
whoa now. I'm not including Trig (although it is helpful in engineering in tons of ways). You'd be surprised at how many times, even still, that I write out the equations and solve them before trying to create a formula in excel. As to multiple differentials, I simply have no remote need, but I know there are a lot of people who do. Everybody needs eigenvalues.
Started an Engineering Major, but about halfway through second year came to the realization I couldn't BS my way so switched to Marketing.
Actually had to use trig the other day to design an angled shelf thing I was building. Worked like a charm.
then I suspect you had a very poor calc teacher, who didn't help you visualize what you were solving. Calculus can be a very visual math, if taught that way. In a huge collegiate setting with bland professor talking formula derivations and such, it's probably a tough subject.
I had to lay out our practice field (was only about 105 yds) using the pythagorean theorem every year. No one else on staff could do it & they wouldn't just stake it off.
I had the same problem in high school. Terrible, terrible calculus teacher. She would work out problems on the overhead projector and had no idea what she was doing. She would look up the answer to see if she did it correctly. Most of the time she was wring.
