Convergent Power Series of sech(x) and Solutions to Nonlinear Differential Equations
It is known that power series expansion of certain functions such as sech(x) diverges beyond a finite radius of convergence. We present here an iterative power series expansion (IPS) to obtain a power series representation of sech(x) that is convergent for all x. The convergent series is a sum of...
