Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.160 Estimate Series Sums and Compare to Models Using Technology skill assessments:

Problem 1Difficulty: Mastery

Two different numerical methods both display a series sum as 0.125 to three decimals. Which statement is most careful?

AThe true sum must be exactly 0.125.

BThe methods prove the sum is rational.

CThe true sums could still differ; matching to three decimals does not guarantee matching beyond about 0.001, and truncation error may exist.

DThe true sum must be between 0.124 and 0.125.

Solution & Explanation:Same rounded display only implies both results lie in overlapping rounding intervals for their displayed values. It does not eliminate truncation divided by algorithm error.

Problem 2Difficulty: Mastery

An app approximates ln(2) using the alternating series 1 - 1 divided by 2 + 1 divided by 3 - 1 divided by 4 +... and displays the partial sum rounded to six decimals. What is the smallest n so that the displayed value is guaranteed to be within 1e-05 of ln(2)?

Solution & Explanation:For the alternating series, truncation error is less than the next term 1 divided by (n+1). Add possible display rounding error 0.0000005. Choose n so that 1 divided by (n+1) + 0.0000005 < 0.00001.

Problem 3Difficulty: Mastery

You want a tighter estimate of an infinite series sum computed by technology. Which action most directly reduces truncation error?

ADisplay more decimal places without changing the computation.

BIncrease the number of terms summed (or use a provably better remainder bound).

CRound each term earlier in the computation.

DSwitch the calculator to degrees mode.

Solution & Explanation:Truncation error comes from leaving out terms or using an approximation algorithm; adding more terms or using a stronger bound attacks that error directly.
