Abstract: This paper addresses approximations to error functions and points out three representative approximations, each with its own merits. Cody's approximation is ...

The definition of freight intensity patterns, mainly on the form of freight trip or commodity generation, is essential in urban economics. Those patters are in general defined in a set of models that ...

The circumference of a sphere is measured to be 24 cm, with a possible error of 0.25 cm. Use the differential \(dV\) to estimate the maximum error in the calculated ...
