The task I am required to solve is as follows:
Consider the (BVP):
{-εx'' + μx' + x^3 = sin(t), where t belongs to the interval [0,π]
{x(t) + x(t + π) = 0
The objective is to compute the solution to the equation and graphically represent, in the same coordinate system, the solutions for:
μ = 1, ε = 0
μ = 0, ε = 1,
ε = μ = 0
μ = ε = 1/10^2
ε = μ = 1/10^3
