Because they got sin and cos to give them a tan
To get to the other tide
She left her Head & Shoulders on the beach
The mathematician says "2" The Physicist says "2, plus or minus 0.1" The engineer says "Probably around 2, but let's say 3 to be on the safe side".
For drinking and deriving
Cos the sine said so!
It is a sin to put it in, but it's a shame to pull it out.
Cos they are afraid of Sin
