Demetris Christopoulos

It is the solution for x(t), so in horizontal axis we always put the independent variable (time t) and at the vertical axis we put the dependent variable (x(t) which here does just an oscillation).

S. Arun

since in the equation the relation was not found between time (t )and displacement (x). How the relation between independent variable (time (t)) and x can be incorporated when solved using the ordinary coding method without using Simulink Mat lab?

It is a very simple ordinary differential equation (ODE), see solution attached.

You should probably study ODE's in order for it to start seems easy.
