Multiple Choices) Please select the correct answer from the following (a) A function f(x) is estimated by using Taylor series in term of g(x). The difference between f(x) and g(x) is called i. round-off error truncation error iii. error order. iv. digit error (b) A presented mumber 1.2345 multiplied by 5.4321 gives 6.70692745. The engineer avoid the digits after to be 6.7059. Then, it is a difference 0.00002745. This difference is called i round-off error. ii. truncation error iii. error order iv. digit error. (c) Bi-section method in finding root of an equation is grouped as bracketed methods because i. the method is divided by two section ii. the root lays inside the bound. iii. it is a well known method. iv. bi-section is an approximation method to find the roots of an equation. (d) From a given 2 dimensions data of (m.), it can be mapped as = {(x). The function is developed by taking error e = (1 - (.)). The reason to take partial derivative of 2 respect to unknown parameters equals to nero because 1. it is to eliminate unknown parameters ii. unknown parameters equal to zero. iii. it gives maximum error iv. it gives minimum error. (e) In curve fitting methods, the coefficient of determination means that I how far error is to model il how fit model to data ill, it is a coefficient of error. iv. how data is usable to model
