Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

recently we've been practising drawing a plot of two-variables functions (we're currently doing metric spaces).

Well, I don't know how to guess the plot for let's say:

[tex]

f(x, y) = \sqrt{x^2 + y^2}

[/tex]

One guy came to the blackboard and drew it quite quickly

Thank you for the suggestions.
