Hi, Plot[] has the attribute HoldAll and you must force Mathematica to evaluate the arguments in the first case Plot[Evaluate[Table[t^c, {c, 1, 2}]], {t, 0.5, 1.2}] Regards Jens Konrad Den Ende wrote: > > I started Mathematica and went: > > Plot[ > Table[t^c, {c, 1, 2}], > {t,0.5, 1.2} ] > but it didn't like it. > > So i computed Table[t^c, {c, 1, 4}] explicitly in an other cell and then > pasted the result into the expression as follows > Plot[ > {t,t^2}, > {t,0.5, 1.2} ] > and then it went well. > > So i have two wonderings. > a) How come there's a difference?! > b) How do i make Mathematica accept what i try to do? > > -- > > Kindly > Konrad > --------------------------------------------------- > May all spammers die an agonizing death; have no burial places; > their souls be chased by demons in Gehenna from one room to > another for all eternity and more. > > Sleep - thing used by ineffective people > as a substitute for coffee > > Ambition - a poor excuse for not having > enough sense to be lazy > ---------------------------------------------------
