Dear friend,

    I have a problem about using Part command of Mathematica: I have the
following output named as cozum (cozum=this output) {{u[t] -> 1.
Power[2.718281828459045235360287471352662497757247093699\

      95957497, 1.732050807568877293527446341505872366942805253810380\

       62806 t] C[1], v[t] ->

   (-0.57735026918962576450914878050195745564760175127012687602 /

        Power[2.71828182845904523536028747135266249775724709369995957\

          497, 1.7320508075688772935274463415058723669428052538103806\

           2806 t] + 0.5773502691896257645091487805019574556476017512\

         70126876019 Power[2.7182818284590452353602874713526624977572\

          4709369995957497,

         1.73205080756887729352744634150587236694280525381038062806 t]

       ) C[1] + (1. C[2]) /

     Power[2.718281828459045235360287471352662497757247093699959574\

       97, 1.73205080756887729352744634150587236694280525381038062806

       t]}}

How should I use the Part command to get only this following part of
this expression:
u[t] -> 1. Power[2.718281828459045235360287471352662497757247093699\

      95957497, 1.732050807568877293527446341505872366942805253810380\

       62806 t] C[1]

Thanks in advance...
