 Author Comment/Response huasheng 06/18/05 1:44pm Dear colleague, Sorry to bother you, but I am indeed really depressed by the equations below: eq1 = DH1[x] == v1*x* DH1'[x] + v2*x*x*DH1''[x] + v3*v4*x - v3* DH1[x] + v5 eq2 = DL[x] == v1*x* DL'[x] + v2*x*x*DL''[x] + v6*(DH2[x] - DL[x]) + v5 eq3 = DH2[x] == v1* x* DH2'[x] + v2*x*x*DH2''[x] - v3*(DH2[x] - DL[x]) + v5 bound1 = DL[XL] == v4*XL bound2 = DH1[XH] == v7*XH bound3 = DH1[XL] == DH2[XL] bound4 = DH1'[XL] == DH2'[XL] DSolve[{eq1, eq2, eq3, bound1, bound2, bound3, bound4}, {DH1[x], DL[x], DH2[x]}, x] The output of DSolve is always the same as input. Your help will be highly appreciated. Thanks a lot URL: ,
