Does anyone know how to solve this problem?

E3.10 (NEW): R-K Variable Step Solvers Controlling stepwise precision in RKF45 (ODE45 in Matlab/Simulink) formulas (see page 122 of the textbook), Zm+1 is a 5th-order Runge-Kutta formula and ym+1 S 4th-order. Their difference is an estimate of the truncation error, used to control the stepwise precision of the computation. (The algorithm is illustrated on slides 66 and 67 of Lecture 5-6 slides.) Find the "ODE12" solver algorithm and it's truncation error, using the same concept by combining the first- and second-order Runge-Kutta formulas.
