Ramanujan type Approximation Formulas
Nikos Bagis
In this article we use theoretical and numerical methods to evaluate in a closed-exact form the parameters of Ramanujan type formulas.
On a General Sextic Equation Solved by the Rogers Ramanujan Continued Fraction
Nikos Bagis
In this article we solve a general class of sextic equations. The solution follows if we consider the -invariant and relate it with the polynomial equation's coefficients. The f…
Generalizations of Ramanujans Continued fractions
Nikos Bagis
In this article we continue a previous work in which we have generalized the Rogers Ramanujan continued fraction (RR) introducing what we call, the Ramanujan-Quantities (RQ). We us…
Evaluations of Derivatives of Jacobi Theta Functions in the origin
Nikos Bagis
In this article using Ramanujan's theory of Eisenstein series we evaluate completely the derivatives of the theta functions and in…
Formulas for the approximation of the complete Elliptic Integrals
Nikos Bagis
In this article we give evaluations of the two complete elliptic integrals and in the form of Ramanujans type- formulas. The result is a formula for w…
The First Derivative of Ramanujans Cubic Continued Fraction
Nikos Bagis
We give the complete evaluation of the first derivative of the Ramanujans cubic continued fraction using Elliptic functions. The Elliptic functions are easy to handle and give the…
