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! Jim_Wendel at ub.cc.umich.edu
