I have used DSolve with some success, but I am wondering if there might not be a better way of using the solver. Here's a trivial example to illustrate... In[17]:= diffeq = x'[t] == t Out[17]= x'[t] == t In[18]:= DSolve[diffeq,x[t],t] 2 t Out[18]= {{x[t] -> -- + C[1]}} 2 In[19]:= sol = %[[1,1,1]] == %[[1,1,2]] 2 t Out[19]= x[t] == -- + C[1] 2 In[20]:= x[0]=1 Out[20]= 1 In[21]:= Solve[sol,C[1]]/.t->0 Out[21]= {{C[1] -> 1}} In[22]:= sol/.C[1]->1 2 t Out[22]= x[t] == 1 + -- 2
