(ìì® Consider the autonomous equation y, = cos(5y) with initial data on the open interval I = a. (1/10) Find all the equilibrium solutions of the differential equation in the interval I. Remark: If necessary, use commas to separate your answers and order them from smallest to largest. Equilibrium Solutions b. (2/10) Find the open interval lincreasing where solutions to the differential equation are increasing. Remark: If your answer contains intervals like (a, b) and (c, d), with b
