Original Message (ID '44547') By Peter Pein:
Hi Andre, then give A its argument. Further note that Derivative takes the derivative of functions, not expressions. Ignoring the minus sign in your input (taking the equation for being correct): DSolve[ Derivative[1][A][t] == -A[t]*(ka + kb + I405*k405 + I488*k488) + kb*c + I488*k488*c, A[t], t] works here. Peter
