If I evaluate, DSolve[{x'[t] == -0.036 x[t] + 0.0124 y[t] + 0.000035 z[t] + 49.3, y'[t] == 0.0111 x[t] - 0.0286 y[t], z'[t] == 0.0039 x[t] - 0.000035 z[t], x[0] == 0, y[0] == 0, z[0] == 0}, {x[t], y[t], z[t]}, t] I receive a massage like this (RootSum::"pfn" : "(DSolve`DSolveDump`dysfunction$6[273147 + <<1>>... is not a pure function.). and them a out in pure notation. But I want to receive the solution in standard notation. Also the same sentece work fine in Mathematica 2.2. Can anyone give a hand?
