Sharper bounds and new proofs of the exponential function with cotangent
This paper provides a Páde interpolation based method for finding improved bounds for the exponential function with cotangent. In principle, it can recover many results in prevailing methods. A new method for proving the corresponding bounds is also proposed, which can also be applied for proving mo...
