Good day, I am pretty sure I do an obvious mistake. I want to plot a Taylor Polynomial of a degree 4 around the point (0,0). So I have created a function: `f[x_,y_]:=Cos[x+y]` Then created a Taylor series up to 4th degree: `Series[f[x, y], {x, 0, 4}, {y, 0, 4}]` I can plot f - function, but trying to plot series returns errors. I believe it is because when doing series, apart from coefficients I will also get a remainder, which could not be plotted. Any help would be much appreciated.
