Question 1 1.1. Use Taylor method to linearize f(x)=3x3+30x when x=3. 1.2. Find the inverse function of the below transform function: F(s)=(s+1)(s2+1)2s+1 Consider the feedback loop in Figure 1 below, where: G=s3+3s2+s+2(2s1) Figure 1. SISO FEEDBACK LOOP Use OCTAVE Using Octave write a program that plots multiple systems (one plot) that have different gain-values for k1=0.45,k2=0.55 and k3=0.60
