Hi I have the following problem: I have solved the first part and found that the system is stable for the sector [0,60.0] with gamma=0.56. I am however unsure how to solve the second part. I have plotted the sector and found the two functions: y1=0.1e3*x^40.5e3*x^30.3e1*x^2 y2=sin(x)*x Where y2 satisfies the criterion but y1 does not. How do I show that the simulation results are consistent with the sector?
