    When Will the Particle Reach Infinity with Given Initial Values?

    Homework Statement At what time does the particle reach infinity given that H(p,x)=(1/2)p^2 -(1/2)x^4. And initial values are x(0)=1 and p(0)=1 Homework EquationsThe hamiltonian equations i believe are given by the partial derivatives let d mean partial derivative so x'=dH/dp and p'=-dH/dx...

    Solve Flows Homework: θ'=1-cosθ, Find T(A) & Behavior at A=0

    Homework Statement θ'=1-cosθ If we have the flow starting at θ(0)=A, determine the amount of time, T(A), that it takes to reach θ=pi and what is the leading behavior as A approaches 0. Homework Equations The Attempt at a Solution Well, in my book, they give an equation T=2pi/w...
