Vertical bar in math environment

Post by sukramix »

Hi,

does anybody know how to create a vertical bar like the one in the screenshot at the end of the line? I tried

Code: Select all

(y-K)\frac{\partial}{\partial y}\frac{1}{2}\sigma_{loc}^2(y,T)y^2p(S,t;y,T)\vert_K^\infty
but this is much too small.

Thanks in advance!

Hi sukramix,

welcome to the board! You could use \right| together with \left. like

Code: Select all

\left.(y-K)\frac{\partial}{\partial y}\frac{1}{2}\sigma_{loc}^2(y,T)y^2p(S,t;y,T)\right|_K^\infty
You could find information about \left, \right, \big, \Big etc. in math docs like those listed in Mathematics with LaTeX, especially in the first documentation called Mathmode.

I've also tried it with \left and \right but I forgot the "." after \left. Now it works! Thx
