The authors present new bounds for approximating the sinc function \((\sin x)/x\), where the unknown \(a_{i}\) and \(\alpha\) are determined using two-point Páde approximation. When compared to previous bounds, it achieves a much better approximation effect. A new method for proving the results is also provided.
