I am assuming what you actually meant by that is
x(t) = 1/4*t^3 + 1
Is that correct?
If so, then in order to investigate the performance of Euler vs Midpoint numerical solution (in the context of this thread) you need to convert that to an initial value problem (IVP) consisting of a differential equation (involving only x, x', and x'') plus initial values for x(t) and x'(t) at some point t=to.
