This is humerous, but likely the result of what I am informed is another case of poor american practice (or practise). arcsin is usually written sin^(-1), and this can cause confusions, since x^(-1) would in fact equal 1/x. However, in the case of sin^(-1) (and other inverse trig operations), it just means arcsin.
I could be wrong about the fact that it's american in origin, but I imagine that's the root of your problem.
