Scientific notebook - plotting 3d surface

AI Thread Summary
To plot the 3D surface defined by the function z = f(x,y) = √(x² + y² - 1) within the domain where 1 ≤ x² + y² ≤ 5, users are seeking step-by-step instructions. The discussion emphasizes the need for guidance on how to visualize this mathematical function effectively in a 3D space, focusing on the specified constraints of the domain. The request highlights a common challenge in mathematical plotting, particularly for surfaces defined by inequalities.

Hi, I wish to plot a 3d surface but as of now have not been able to!

I wish to plot z=f(x,y)=[x²+y²-1]^1/2 restricted to the domain:

dom(f) = {(x,y)|=1 ≤ x² + y² ≤5}

Any step by step instructions would be greatly appreciated!
Thanks in advance!
