A series expansion of a logarithmic expression and a decreasing property of the ratio of two logarithmic expressions containing cosine
In this study, by virtue of a derivative formula for the ratio of two differentiable functions and with aid of a monotonicity rule, the authors expand a logarithmic expression involving the cosine function into the Maclaurin power series in terms of specific determinants and prove a decreasing prope...
