' Equation: X''(t) =  Sin[w * x] - x

w=6

G{t,x,y} = Sin[w*x] - x

to =0 :  tf = 8:  xo =1  :  yo = 0       ' yo  is the same as X'{xo}

' Try 0.2 for both scales prior to generating the family.
' NOTE: Turn axis off ntil all graphs are completed. Then, turn on the axis option if
'    you wish. This action avoids multiple "Y" symbol generation ( due to auto axis).
