At the last conference of Nigeria Society of Engineers (NSE), a mechanical engineer presented a paper on the “Effects of Noise on Machine Operator”. In the work, he developed a mathematical model using Taylor’s series and carried out all the computations to four decimal places.
i. identify the possible types of numerical error that might have been committed by the engineer during the computations.
ii. Define the errors and state how they can be minimized.
