Nested cos() calculation in Oracle 10

I have table with some positive integer numbers

n----12510

For each row of this table I want values cos(cos(...cos(0)..)) (cos is applied n times) to be calculated by means of SQL statement (PL/SQL stored procedures and functions are not allowed):

n   coscos--- --------1   12   0.5403023058685   0.79348035874310  0.731404042423

I can do this in Oracle 11g by using recursive queries.
Is it possible to do the same in Oracle 10g ?
