How do you do this (evaluation symbol) with a tall bar, similar to integral? $\displaystyle {^{a}}_{a}$ Thanks Last edited by zylo; September 13th, 2018 at 06:46 AM.

$\displaystyle (xa)\biggr\rvert_{a}^{b}$ I figured it out using integration symbol as a model and looking up bigger vertical bar: "(xa)\biggr\rvert_{a}^{b}"

$$\left. x + \cos x\right_a^b$$ Code: $$\left. x + \cos x\right_a^b$$ Code: $$\left. x + \frac{x^2}{2}\right_a^b$$ $$\left. \begin{aligned} x+y&=3 \\ xy&=1 \end{aligned} \right\} \implies \left\{ \begin{aligned} x &= 2 \\ y &= 1\end{aligned} \right.$$ Code: $$\left. \begin{aligned} x+y&=3 \\ xy&=1 \end{aligned} \right\} \implies \left\{ \begin{aligned} x &= 2 \\ y &= 1\end{aligned} \right.$$ Last edited by v8archie; September 13th, 2018 at 10:19 AM.
