A power series in 'x' involves factors where an 'X' is added to a constant, and raised to a power, forming infinite terms. Learn how to build a...
The steps associated with finding the power series of ln(1 - x) include:Deriving the power series for a related function, 1 / (1 - x) Integrating to find the power series for ln(1 - x) Determining the interval of convergence. To find values of x that allow us to use the power ...
In a previous paper, we developed a power series representation and estimates for an effective action of the formln[∫ef(α1,…,αs;z,z)dμ(z,z)/∫ef(0,…,0;z,z)dμ(z,z)]. Here,f(α1,…,αs;z,z)is an analytic function of the complex fieldsα1(x),…,αs(x),z(x)...

Power Series Representation; Radius of Convergence:The convergence of a power series [f(x)=∑n=0∞an] depends on the limit of the ratio of its consecutive terms (an,an+1). It may happen that the value of this limit remains less than unity for certain values of argument (x) then...
