Use Matlab so solve the problem.

1) Consider the Autonomous Differential Equation y cos y y. a. Plot the function f(x) -cos. 2 on the interval [-2, 2 b. Find the stationary solutions to the autonomous equation using the 'fzero' command in Matlab. c. For what range of y-values is the solution increasing/decreasing? d. For what range of y-values is the solution concave up/down? e. Use your ode45' to solve the IVP with y(0)0 on the interval [0, 10 and plot the solution
