Rules and Formulas  Supplied or Not?

I was having a chat to a teacher of senior (ie grade 11 and grade 12) mathematics a few days ago, and the question of whether students should be given rules, identities and formulas on exams was raised. The question was raised in the context of trig identities and index laws, but obviously has wider applicability. Should we supply on the exam paper such things as sin^2 + cos^2 = 1, (ab)^n = a^n b^n, log(ab) = log a + log b, the chain rule for differential calculus, etc,, and concentrate on whether students can apply the correct rule correctly. Or are these part of the body of mathematical knowledge that a good student should have at their fingertips?
In Queensland, we have external exams for mature age learners. The Maths in Society exam has the formulas supplied, the Maths B and Maths C exams (roughly equivalent to Algebra II, and Calculus and Analytical Geometry) don't. So even within our system there appears to be differing attitudes.
I would be interested to find out what other teachers at this level think.
