Solve x′′ = −x − α(x2 − 1)x′, 0 ≤ t ≤ 30, with the initial conditions x(t = 0) = 0.5 and x′(t = 0) = 0, using RK4 method in your computer where α = 1. Plot the solution.

There are many people on this forum that can write the code for this, but we don't do that for homework problems. You must show some effort first, and then we can help you solve your coding problems. To code an RK4 scheme from scratch, I would first suggest you look at the equations here and try to code them up:
The RK4 equations are spelled out. Just remember that your "y" and "k"s will be 2-element vectors since you have a 2nd order ODE to solve.
