What does this symbol mean?
Could you people help me a little? I Donít understand what this symbol means. Itís that weird vertical line at the right side of the equation.
What does the line and that ďT=0Ē mean? I have never seen that before, and now Iím stuck! I canít study more before I know what that line means.
So If you guys could help me a little I would greatly appreciate it :)
(PS. My English might be a little weird because itís not my native language. But try to understand what Iím trying to say :) )
