Are questions about the names of things in mathematics on-topic on math.SE? If not, can they be asked in Meta?
I am quite good at mathematics but often I don't know what things are called. For instance, I wanted to find the area under a curve for a particular function. I looked up the name of the function on Wikipedia and there was a huge amount of information. I didn't know what I was looking for was called integration until I posted a question on math.SE. Someone left a comment saying that the information I wanted was given in detail on the Wikipedia page, which once I knew what the name was I was able to verify.
So, where is the best place to ask what things are called?
