سوال ۲۲ کنکور ارشد ریاضی ۱۴۰۲

PASSAGE 3 (excerpt). "For modest accuracy requirements, Runge-Kutta-Fehlberg methods with low orders of approximation p are to preferred. Runge-Kutta-Fehlberg methods of certain orders sometimes react less sensitively to discontinuities in the right-hand side of the differential equation than multi-step or extrapolation methods. It is true that in the absence of special precautions, the accuracy at a discontinuity in Runge-Kutta-Fehlberg methods is drastically reduced at first, but afterward these methods continue to function without disturbances. In certain practical problems, this can be an advantage."
