Thanks! It works fine, but now I have another difficulties. How can I make automatic substitution of zero argument, i.e. K1(0) = 1, K2(0)=K3(0)=K4(0)=0? Also, fsolve doesn't seem to work with these functions. And another problem:

a^3*l^3+a^3*l^3*cosh(a*l)*cos(a*l)-6*sinh(a*l)*cos(a*l)+6*sin(a*l)*cosh(a*l)

when I try to solve it with respect to a*l Maple can't seem to recognize that a^3*l^3 = (a*l)^3, what should I do?

Thanks in advance.

Thanks for the code! I think I get the idea now.

>>What do you plan to do with them?

I just need to make Maple understand that (K1)' = K4, (K2)' = K1, etc. Just like it operates with sinh and cosh.
