•Suppose you want the value of d 2 g/dy 2 for y =2.•What does the following give you?>> y = 2, diff2_g•So use subs command (see >>help sym/subs).>> diff2_g2=subs(diff2_g,2)•If you have more than one variable, you must use thefollowing syntax:subs(expression,{var1,var2 ...},{value 1, value 2, ..})•Exercise: find diff_f for x = 1, a = 2, b = 3, c = 4(remember f = e -ax x 3b sin(cx), diff_f=df/dx)134
