Multiple-correction and summation of the rational series
Xiaodong Cao, Cristinel Mortici
The goal of this work is to formulate a systematical method for looking for the simple closed form or continued fraction representation of a class of rational series. As applicatio…
Accurate approximations of some expressions involving trigonometric functions
Marija Nenezic, Branko Malesevic, Cristinel Mortici
The aim of this paper is to apply an original computation method due to Malesevic and Makragic [5] to the problem of approximating some trigonometric functions. Inequalities of Wil…
Some inequalities for the trigamma function in terms of the digamma function
Feng Qi, Cristinel Mortici
In the paper, the authors establish three kinds of double inequalities for the trigamma function in terms of the exponential function to powers of the digamma function. These newly…
Asymptotic series and inequalities associated to some expressions involving the volume of the unit ball
Cristinel Mortici
The aim of this work is to expose some asymptotic series associated to some expressions involving the volume of the n-dimensional unit ball. All proofs and the methods used for imp…
