Trigonometry Song

Sing to the tune of Jolly Old St. Nick: Angles in trigonometry aren't so very hard, / Sine of zero is a zero, 30 is one half, / Forty five has square root 2 over 2 you see, / Sixty is root 3 over 2 and ninety is a one. (Have to sing this line kind of fast) // Cosine is the same you see only in reverse, / Put your numbers in a chart just as in this verse, / When you get to tangent dear, use this fraction there, / Sine over cosine is the thing that will end your work. Sometimes my classes really like to sing and the ones that don't will respond if you sing part of a line so they do remember the values.
