Not sure the title has the correct terminology but I'd like to evaluate the following definite integral:
Does this require the same approach as
effectively returning the additive inverse?
Or is there some kind of voodoo that must be done, such as perhaps using $[-∞, ∞]$ as limits of integration and then subtracting using $[1,5]$?
Also, what does it mean? Does it represent an area as well?
