Homework Statement
Its about a system like in picture. I have it solved alredy BUT I still have a problem
After getting the dynamic equation by Newtonian and Lagrangian methods I solved one of them making the hipótesis of Little oscillations. This diferential equation has three solutions depending on ω.

Homework Equations
The problem is that one of them is: θ=θocosh(Ωt) but when we increase t, θ grows exponetially till the infinite! How can this be posible if this is a solution only suitable for small oscillations?
Thanks!
PD: sorry about my english (Im spanish, and I am very tired now)
