Matlab- differential equations

Can someone please help me solve this problem on matlab. I don't know where to start.

Thanks

9. (25 pts) (Take Home Problem) The mathematical model for the Forced Van der Pol equation, is: esin(wt) a) Write a code in Matlab and call the Script file: Van Der Pol, to solve numeric the equation in c 0 with y (0) 0.1, y (0) v% to 0.1, and u 3. Plot r2 t and the phase space zi z2 the t-interval [0,250]. b) Solve numerically the equation when E 1 with y(0) yo 0.1, y (0) y% vo 0.1 w 1, and Au 3. Plot z2 t and the the phase space z r2 in the t-interval (0,250] c) Solve numerically the equation when 3 with y (0) 3, y'(0) y% vo -5, w 5, and Au 3. Plot t and the the phase space zi z in the t-interval [0, 250
