| Abstract: | Three methods of solving the external driven oscillator system are discussed. The first using operator equation in the Heisenberg picture,the second using the coherent state expectation values to search for the time evolution operator and the third by quantum invariant theory.The two later methods are equivalent and the first method cannot determine the quantum phase factor. |

| Keywords: | time dependent oscillator system quantum phases time evolution operator |
