Transforming a polynomial into a trigonometric format tia sal2

Greetings All

I'm using mathematica 6 and I have a polynomial and would like to
convert it into
a Trigonometric format.  Is this possible?

Example:
I have a polynomial
0.00154991- 4.01371 x + 1.81197 x^2 + 8.00183 x^3 - 9.3462 x^4

How can I transform this into a trigonometric format
Example:
0.00596679 Cos[6.98132 x] + 0.00358397 Cos[7.21403 x] +
 2.25013 Sin[0.232711 x] - 4.51511 Sin[0.465421 x]

 Note: these aren't correct answers I just wanted to include and
example

 tia sal2
