New bounds for the exponential function with cotangent

Abstract In this paper, new bounds for the exponential function with cotangent are found by using the recurrence relation between coefficients in the expansion of power series of the function ln(1−2x2/15−px6) $\ln (1-2x^{2}/15-px^{6})$ and a new criterion for the monotonicity of the quotient of two...
