RKF
Uses a list [z)—containing the name of the time
variable, the name of the solution variable, and the
differential fimction—and the absolute error
tolerance (^) to compute the solution of the initial
value problem at a point (r) using the
Rimge-Kutta-Fehlberg (4,5) method.

RKFERR
Uses a list (y)—containing the name of the time
variable, the name of the solution variable, and the
differential fimction—and a possible step size (.r)
to compute the change in solution and an absolute
error estimate for that step using the
Runge-Kutta-Fehlberg (4,5) method.
