Question: Assume that x, y, and z are MATLAB arrays initialized as follows:

x = linspace(0,2*pi, 100);

y = sm(x);

z = exp(-x);

Write a MATLAB fragment that plots the function e-x sin(x) across the interval [0,47r]. To receive full credit, the fragment should not involve any additional calls to sin or expo Exploit the fact that sin has period 27r and that the exponential function satisfies e^a+b = eae^b.
