Talk:Quadrant (plane geometry)

What is meaning of "All","Science","Teachers","Crazy"?

edit

What is the meaning of the words "All", "Science", "Teachers", "Crazy", in the example coordinate plane? Each of the four words is in each of the four quadrants, first through fourth, respectively. Is this some kind of mnemonic? 68.35.173.107 (talk) 03:51, 13 July 2015 (UTC)Reply

It's a mnemonic for which trigonometric functions are positive in the quadrant:
All: all
Science: sine
Teachers: tangent
crazy: cosine
