thank you it is much simpler than i expected

they are the ones written in the equation i provided 0 for mass zero and N for mass N thats all what was provided

then my book provided a result from the boundary conditions and this is where i reached a different result from them

then we where asked to move to finite number of masses we already the space of the solutions without conditions upon the system we added conditions on mass 0 and N not small n it was a problem on my part so the condition up are on 2 masses only the one at the start of the spring and at the end...

i will try to phrase the problem the ##\psi_n(t)## indeed represent the displacement of the ##n##th mass from equilibrium at any time ##t##, the full problem is as follows we had a set of masses n masses (an infinite number ) that are coupled on a spring with spring constant k for all and they...

since then i can understand but dealing with t as a variable i am not reaching anywhere

oh do you mean since it is zero at all times it is also zero at t=0 so i can deal with a nicer version of the problem and reach the result ?

the solution for the infinite num case the problem is that i only could reach the condition that the coefficients are zero when i substituted n=0 , i am reaching two independent variables i am not sure what am i doing wrong that's preventing me from getting a similar result to them "that...
