Use 4th order runge-kutta method with step size h 02 and h

Question

Consider the initial value problem

dy/dt = 1 - t³/y with y(0) = 1 

i) Use Midpoint Method with step size h =0.2 and h =0.1 to find y(2);

ii) Use 4^th order Runge-Kutta Method with step size h =0.2 and h =0.1 to find y(2).

iii) Sketch all the solutions on the interval [1, 2] with appropriate legend for comparison.
