What is the name of the vertical bar?
When taking a definite integral, the first step is finding the anti-derivative. Once you have gone through all the steps to complete that, you need to evaluate the anti-derivative. This is often written with the formula for the anti-derivative then a vertical bar after that formula with the upper and lower bounds, much like the integration symbol. What is this vertical bar called? Does it have a name? For that matter, does the integration symbol have a name?
This isn't for homework, but neither is it just out of curiosity. I have a reason for wanting to know this, but it would take a while to explain.
