Two mathematicians are studying a convergent series.
The first one says: “Do you realize that the series converges even when all the terms are made positive?”
The second one asks: “Are you sure?”
Two math students, a boy and his girlfriend, are going to a fair. They are in line to ride the ferris wheel when it shuts down.
The boy says: “It’s a sin for those people to keep us waiting like this!”
The girl replies: “No – it’s a cosin, silly!!!”
