Ar. Yaakub et Dj. Evans, HIGH-ORDER INTEGRATION FORMULA USING TRIGONOMETRIC POLYNOMIALS FOR PERIODIC IVPS, International journal of computer mathematics, 66(3-4), 1998, pp. 277-297
In this paper a new fifth order Runge-Kutta type method for solving os
cillatory problems by the use of trigonometric polynomials is proposed
which extends the earlier work of Gautschi [1961]. An analysis of the
convergence and stability of the new method is given with comparison
with the standard Runge-Kutta methods. Finally numerical results are p
resented which confirm the accuracy of the high order method.
