Two quasi-bugs in Macintosh II Mathematica:
(1) Plot something that lies wholly in the first quadrant but give option
axes ->{0,0} with the intent of seeing the plot with nice axes; you will
get partial axes, seemingly defined by the ranges of abscissas and ordinates
in the plot. Example:Plot[x^2,{x,2,5},Axes->{0,0}] produces rather an
ugly display.
(2) DSolve[{y''[x]+y[x]==0,y[0]==1,y'[0]==-1},y[x],x] gives the rule
y[x]->Cos[-x]+Sin[-x]. This is correct, but not as natural and nice to see
as Cos[x]-Sin[x]. At least such is my opinion!
