I have the following function:
teht4 [x_, y_] :=
x*Sin [y] /; (x >= \[Pi] && x <= \[Pi] && y >= \[Pi] && y <= \[Pi])
Plot3D[teht4[x, y], {x, Pi, Pi}, {y, Pi, Pi}]
The following things should be done to the plot:
a) changing the plot so that the width of the graphics is twice as much as the height
b) naming the plot as x sin(y)
c) giving some names to the x and y axis
d) drawn the axis so that the intersectional point is in (2 \[Pi], \!\(TraditionalForm\`1\/2\))
How to do these??
