Hi i have a problem for writing a runge-kutta 4th order matlab code for solving this equation:

sinθ = 0

can somone help me?thnak you in advance

@ali mafi, are you interested in only the numerical solution, or the solution has to be produced from the 100% pure RK4 algorithm?

Convert the 2nd order ODE in a system of 1st order. Then either call ODE45 or use your own RK4 code.

What have you tried so far? Which problems occur? What is your question related to Matlab?
