******That doesn't mean, though, that they should actively memorize 5*5, or what the sine of π/2 is. Your teacher should simply make sure that you need the result so often, working it out yourself if necessary, that you memorize it automatically. If you forget a formula, derive it yourself again. Without looking it up. Of course, one could argue that this is also a way of memorizing.****** I disagree. They should actively memorize 5*5 and all their other basic addition, subtraction and multiplication facts. Now, I wouldn't consider the sine to be a basic math fact.

The sine of Pi/2 is. (It's "1" BTW)
