(One of) The most famous trigonometric identity? ;) You'll generally find it in a list titled that way.
 
I think it's called the Pythagorean identity.
 
Thanks a lot, both of you. The name for it in my native language has been highly influenced by the number "1" :/
 
What would it be called in your native language? In Danish it is readily called "Idiotformelen" -- the idiot formula...
 
That was funny. It would be "trigonometriska ettan" or "(the) trigonometry 1"
