Does sin(gerine)/cos(gerine) equal a tangerine?

I believe so......

Here's another one....

Prove that

Sin (x)  /  n       =    6

OK, that was hilarious.

Another one:

A math teacher and a textbook get kicked out of a bar. The textbook asks, "Why'd we get kicked out?" The math teacher replied, "cos(you)."

Get it?
