The following lines of MATLAB code evaluate the function 2r at 15-10-16 in four different ways (a) x = 1.5e-16; x = 1.5e-16; 1.5e-16; x1.5e-16; f= 0.5* ( (exp (x)-exp (-x))/x) f=0.5* ((exp (x)-exp(-x))/((x+1)-1)) f (b) (c) =0.54((exp (x)-exp(-x) ) / ( (x-1)+1)) f(exp (x)-exp(-x))/((x+1)+(x-1)) x= (d) What are the four computed values of f, if IEEE floating point arithmetic is used? You can assume texp) and exp-) are calculated exactly and then rounded to the nearest floating-point number. Hint: From Taylor's theorem, exp(E) x2 3! for some between 0 and 2.
