Thanks Kitonum 19099 and sursumCorda 20.

Both methods solve this puzzle symbolically.

Tokoro. :RLC circuit I want to solve.      (1)  (2)  (3)  (4)  (5)     (6)

Solve eq(6) by Maple's dsolve.

@Preben Alsholm It makes equation (7). And I want to solve this ODE in Eq.(7) by Maple.

Using laplace convertion, I can get the answer and can plot it.

@acer Thanks show me the power of Maple.

@dharr @Carl Love is right. Surprisingly, both are planar. I only know this very fameous math problem. I only know the answers and don't know how to solve. I rewrited this math problem to the electric circuit problem.

@dharr Yes, "all currents are different and none of them are zero".
Please try to calculate the resistance of node 1 to 13. This is very good electrical engineering problem that without using computer math software, such as Maple, not only students but also professors can't solve.
