I wish to plot a function in 3d (let's say cosine) with x and y as parameters.

I know the plot3d command in Maple is as follows:

Code:

`plot3d(cos(x+y),x=-1..1, y =-1..1);`

My question is this: how would I modify the increment values of x and y which are plotted?

For instance I want x=-1 to 1 but only in 0.25 increments and y=-1 to 1 in 0.1 increments.

A second question is: How do I display each value for what maple is plotting in 3d?

for instance:

f(x,y) = cos(x+y) => f(x,y) = ?

x = some value between -1 and 1 (in 0.25 increments)

y = some value between -1 and 1 (in 0.1 increments)

for question 2, basically i'm looking for something like [seq(f(x),x=a..b,increment)]
