They are going to have fun in university.
When asked for a formula sheet for a tut, the lecturer wrote this on the board.

It's actually a major problem IMO, kids in school get these formulas without knowing where they come from.
Whats the english name for the top left one? Midnight formula?
And in the real world this helps didly squat!
We were allowed to use calculators, even HP scientific calculators, we were allowed formula sheets and in some courses even the textbook. The fact is that a calculator and even the book doesn't help you much to solve advanced problems. The calculator is only good for the very last step of calculating the final numbers. Textbooks only help if you know where to look or are good at quickly locating information. Formula sheets only help if you know which formula to use. In other words just like the formula sheet in this thread they're not much help at all unless someone knows what they're doing.And when you get to university, you get no formula sheet or even the use of a calculator. A lot of the "smart" kids got a rude awakening.![]()
It's not problem at all. In fact it's just like much of university engineering and science, knowing where they come from might help you derive it from first principles, but you don't need to know that to use a formula you're given, remember or have on a sheet. I was actually quite surprised when I got to university and suddenly memorising formulas was no longer a requirement (which it stupidly was when I went to school).It's actually a major problem IMO, kids in school get these formulas without knowing where they come from.
That's as good as saying "we know you know nothing at all".Tₙ = a + (n-1) d
