[SOLVED] The symbol for |
I want to know the symbol for big |

That is if I want to write $\int^{0}_1 \frac1{x+1} \, dx = \ln|x+1| |^{0}_{1}$

The last symbol( that looks like |) is really small.... How do I normalise it to the size of the rest of the symbols?

thanks,
Iso

and to evalutate put this [tex]\bigg|_{1}^{0}[tex] gives you $\bigg|_0^{1}$

It depends, or just make \big|_0^1, \Big|_0^1, \bigg|_0^1, \Bigg|_0^1.
