The sinc function is used very often in optics and is de ned by the equationsinc(x) =sinxx;x6= 01;x= 0(Hint: look up the keywordsincin the Matlab help document for the description and how touse.) Plot the following functions fromx=5 tox= 5 on the same gure with di erent linecolors. Be sure to add a legend. Then, graph the functions on four separate plots on the same gure and title each subplot.(a) sinc(x)(b) sinc(x+ 2)(c) sinc(x=3)(d) sinc(x)sin(x)

(Hint: look up the keyword sinc in the Matlab help document for the description and how to use.) Plot the following functions from z =-5 to z = 5 on the same figure with different line colors. Be sure to add a legend. Then, graph the functions on four separate plots on the same figure and title each subplot (a) sinc() (b) sin(+2) I need the MATLAB code please (d) sinc(r)sin()
