Carry out a backward error analysis for the calculation of


Question: Carry out a backward error analysis for the calculation of the scalar product s = a1b1 + a2b2 + . . . + anbn Redo the analysis under the assumption that double-precision accumulation is used. This means that the double-precision results of each multiplicatioin are retained and added to the sum in double precision, with the resulting sum rounded only at the end to single precision.
