Several sharp inequalities involving (hyperbolic) tangent, tanc, cosine, and their reciprocals
Abstract In the paper, in view of two monotonicity rules for the ratios of two functions and of two Maclaurin power series expansions, the authors establish several sharp inequalities involving (hyperbolic) tangent, tanc, cosine, and their reciprocals.
