That's true, but giving the formula makes the problem way easier : You know you have to use that formula in the problem. That's less intellectually challenging.

The best is to give the students a cheat sheet with a lot formulas, but not a reminder in each exercise of which formula is useful in that exercise.
In that case they have to think about which one to use.

We don't want people to learn formulae. We don't particularly need people to do mental arithmetic. We want people to understand problem solving and gathering information and relationships between different bits of the formula.
