There are two examples of what I am talking about in this equation: $$\displaystyle \left.\mathrm{d}\Phi\left(v\right)\right|_{p}\equiv\left.v^{\mu}\frac{\partial\Phi^{\lambda}}{\partial x^{\mu}}\frac{\partial}{\partial y^{\lambda}}\right|_{\Phi\left(p\right)}.$$
They are the vertical bars that inform the reader what value is used for evaluation of the preceding expressions.
When I try to produce such a result, the bar resizes inappropriately. I want this this for text and display equations, not form input. Is there a way to accomplish what I am asking for?
