Abstract: This paper proposes a novel approximation for the exponential integral function, E 1 [x], using a sum of exponential functions. This approximation ...

Founded in 1888, to further mathematical research and scholarship, the 30,000-member American Mathematical Society provides programs and services that promote mathematical research and its uses, ...

Abstract: Multidimensional small baseline subset interferometric synthetic aperture radar (MSBAS InSAR) is a multidimensional deformation time series inversion method that integrates multiorbit SAR ...

This paper provides a numerical technique for determining the parameters in a model expressible as the sum of exponentials. The essence of the method is to rewrite the model so that after ...

Finding the area under a curve is a central task in calculus. This process is called finding the definite integral. Microsoft Excel does not have native calculus functions, but you can map your data ...
