In this note our aim is to extend the Huygens type inequalities to the Bessel and modified Bessel functions of the first kind. Our main motivation to write this note is a recent publication of Zhu, which we wish to complement.
Keywords: the Bessel functions, the modified Bessel functions, Huygens type inequalities
