Question: Integration constants help

Hello, I appreciate this forum because NOT one of my questions has been answered by the Maple help, which I think is very poor. The question I am working with has to do with the arbitrary constants that maple puts into the solution to differential equations. I have two differential equations which, when solved, will be set equal to each other. Now the equations are second degree so they both have two constants associated with their respective solutions. The problem is that when I set the solutions equal to each other, the constants will be different, but I can't seem to rename them from the standard _C1 etc. Here is what I tried: T[tot] := T[1](x) = T[2](x,_C1=_D1,_C2=_D2); but this just returned the expression for T[tot] as if I never put the extra argument into T[2] in the first place. Additionally, I know from physical considerations that _C1 in T[2] is zero, but the attempt below does nothing. T[2] := T[2](x,_C1=0); How can I reassign these constants? Thanks.
