Conclusion:   The solution derived using the Runge-Kutta method O("RK_3_EN_18.gif") is in the form of a table of the variable function y(x), shown in the second column of the table above.  Since the  local apriori error of the method is O("RK_3_EN_19.gif") (or global error is  O("RK_3_EN_20.gif") ) and here h=0.1, then these solutions must be rounded to three symbols after the decimal point.
