Abstract:A new method of trigonometrically fitted method was developed based on the fourth algebraic order predictor - corrector method. The local truncation error of the new method was analyzed, and the regions of absolute stability were given. Some numerical experiments show that the new method is more efficient than some other methods when dealing with initial value problems with oscillating scheme.
Keywords:initial value problems with oscillating solutions  trigonometrically fitted  predictor- correc- tor sch
