Problem 1: Consider the function f(x) = a1 sin(a2x) + cos(G4x) where a1, a2, a3, and a4 are parameters 1.1) Write a user-defined function for f(x) provided that x is a vector. (5pts) 1.2) Plot f(x) for x-|0,6m, a1-1, a,-2, a3-3, and a4-4. Make sure to put axes labels. (Spts) 1.3) On a new single plot window, plot f (x) for the same parameters values defined in part 1.2 but a3 0.4,0.6,0.8,1,1.2,1.4,1.6,1.8,2). Make sure to put legends defining each curve.
