Abstract


This Research employs both Taylor theorem of expansion and Binomial Coefficient expansion to develop a mathematical model for error which propagates in Engineering Calculations that involve single variable function. Verification of the model was done through computer simulation by comparing the result of the model with the actual difference between the result given by the function in question, when computed with ‘error variable’ and the same function when computed with ‘error free variable’. The output from the model proposed, gave good results for error propagation that were not significantly different from that obtained from the actual difference between the results of the function computed with ‘error variable’ and ‘error free variable’.

Key words: Development, Mathematical model, Error propagation, engineering calculation, single variable functions
