Grid in math

Question

How can you build a finer grid, for example, with non-target values ​​or something else? My function is defined only for a very narrow range, and Id likes to visualize it better with a grid. Also how do you make the function white? No "white" ColorData.

Answer 1

Your color question:

The default color is white for scenes, with the default color light used to make the graph look white.

You can use the Lighting ( Lighting -> "Neutral") parameter to get opaque lighting in 3D graphics. Then the result will be white / grayscale:

Plot3D[Sin[x y], {x, 0, 3}, {y, 0, 3}, Lighting -> "Neutral"]

Your grid question:
