Brian Winkel recently gave a comparison of differential equation notation in Maple and Mathematica. I don't want to start a religious war over symbolic algebra systems. (Maple makes and plots the same sort of numerical solution Brian got with Mma.) I do want to point out that to be fair, the original Maple example (which Brian got from elsewhere) was written in a really awful way. It could also have been written (a*t^2+b)*(D@@2)(f)(t)+c*t*D(f)(t)+d*f(t)=e This still isn't as neat as Brian's (a t^2 + b) f''[t] + c t f'[t] + d f[t] == e but it isn't the horror that was posted. I think Mma wins on this one, but it isn't the shutout it looked like in the original post. --- Tim McLarnan tim at math.earlham.edu Dept. of Mathematics, Earlham College, Richmond, IN 47374
