Plot3D[x^2 - y^2, {x, -5, 5}, {y, -5, 5}, AxesLabel -> {x, y, z}]To input a function with two variables in Mathematica, use the syntax f[x_,y_]:=expression, where "f" is the name of the function, "x" and "y" are the variables, and "expression" is the mathematical expression involving x and y. For example, f[x_,y_]:=x^2+y^2 would define a function of two variables that computes the sum of their squares.
To plot a 3D graph of a function with two variables in Mathematica, use the Plot3D function. For example, Plot3D[x^2+y^2,{x,-2,2},{y,-2,2}] would plot the function f(x,y)=x^2+y^2 over the range -2 to 2 for both x and y. This will create a 3D graph with x and y as the axes and the values of the function as the z-axis.
Yes, you can add labels and titles to your 3D graph in Mathematica. Use the AxesLabel option to add labels to the x, y, and z axes, and use the PlotLabel option to add a title to your graph. For example, Plot3D[x^2+y^2,{x,-2,2},{y,-2,2},AxesLabel->{x,y,z},PlotLabel->"Graph of f(x,y)=x^2+y^2"] would add labels to the axes and a title to the graph.
To change the color or style of your 3D graph in Mathematica, use the ColorFunction and PlotStyle options. The ColorFunction option allows you to specify a color scheme for your graph, while the PlotStyle option allows you to change the style of the graph lines or surface. For example, Plot3D[x^2+y^2,{x,-2,2},{y,-2,2},ColorFunction->"Rainbow",PlotStyle->Thick] would plot the function in a rainbow color scheme and with thicker lines.
Yes, you can add a legend to your 3D graph in Mathematica. Use the PlotLegends option to specify the labels for the legend. For example, Plot3D[x^2+y^2,{x,-2,2},{y,-2,2},PlotLegends->"f(x,y)"] would add a legend with the label "f(x,y)" to the graph. You can also use the LegendLabel option to add a title to the legend.
