I have a function`R1[x_, t_] = -((t^35 x^2)/10333147966386144929666651337523200000000)`; I use the following command in Mathematica to show the graph of Function pic1 = Plot3D[Abs[R1[x, t]], {x, 0, 1}, {t, 0, 1}, PlotRange -> Full, AxesLabel -> {"x", "t"}, AxesEdge -> {{-1, -1}, {-1, -1}, {-1, 1}}, LabelStyle -> Directive[Black, Bold, 14], BoxStyle -> Directive[Thick, Black, 16], BoxRatios -> {1.5, 1.5, 1.5}, ViewPoint -> {-2, -2, 1}, PlotStyle -> Green] The Image is not shown [![enter image description here][1]][1] But when I am using the following Function R2[x_, t_] = - ((t^35*x^2)/10333147966386144929666651337523200000); I have just removed three zero from the denominator, Mathematica gives the Image of function using same code pic1 = Plot3D[Abs[R2[x, t]], {x, 0, 1}, {t, 0, 1}, PlotRange -> Full, AxesLabel -> {"x", "t"}, AxesEdge -> {{-1, -1}, {-1, -1}, {-1, 1}}, LabelStyle -> Directive[Black, Bold, 14], BoxStyle -> Directive[Thick, Black, 16], BoxRatios -> {1.5, 1.5, 1.5}, ViewPoint -> {-2, -2, 1}, PlotStyle -> Green] The Image of Second Function is [![enter image description here][2]][2] [1]: https://i.sstatic.net/oTxBPksA.png [2]: https://i.sstatic.net/4RaSWbLj.png How we obtain the Image of 1st Function. I am using Mathematica 13.3.1
