Math & Science ⇒ Partial derivative "evaluated at" value

[ccrummer]

I want to show the "evaluated at" value at the right of a vertical line but I don't know how to place it at the bottom of the line.

$$ \vec{\tau} = \mu {{\partial{\vec{u}} \over \partial{y}}\vline_{y = 0}}. $$

The "y = 0" typesets too high.

Thanks

You better use correct LaTeX syntax for typesetting math expressions.

Code: Select all

\[
  \vec{\tau}=\mu\,\frac{\partial\vec{u}}{\partial y}\bigg|_{y=0}
\]

Take a look into lshort, l2tabu and "Math mode".
