Sharp Cusa type inequalities with two parameters and their applications

Sharp inequalities for tangent function with applications

“…[ 8 , 20 – 23 ]). Some refinements and generalizations of Cusa’s inequality can be found in [ 8 , 21 , 22 , 24 – 29 ]. Now by letting and simplifying, inequalities ( 4.4 ) and ( 4.5 ) can be written as which give stronger versions of Cusa’s inequality.…”

Frame’s Types of Inequalities and Stratification

“…The aim of future research is to consider other classes of inequalities in a similar way, by combining different methods with the concept of stratification. In that regard, we refer the reader to papers [6,[15][16][17][18] for understanding the latest progress in the field.…”

A two-point-Padé-approximant-based method for bounding some trigonometric functions

“…The Wilker inequality, which involves the trigonometric function has been discussed in the recent past; see also [ 2 , 3 , 6 – 9 , 11 – 15 , 17 – 23 ] and the references therein, such as the following ones in [ 14 , 18 ]: where , , , .…”
