El. Consider the autonomous ODE below in which a is a constant (real number): V = a+ cos(y) a) For what value(s) of a, if any, would there be no critical points (equilibrium/constant solu- Rions)? b) For what value(s) of a, if any, would all critical points (equilibrium/constant solutions) be semi-stable?

b) Find the order of Z=0 for the following functions: 3) (e²²-1-7²) Sin³z
