Both Sides Now Humorous Satire

To be sung to the tune of Both Sides Now by Judy Collins Rows and rows of subtrahends Repeating decimals without end Regression lines to mark a trend I've looked at numbers that way But now they only add up wrong Even though I stayed up all night long Like missing words in someone's song Words that seem to say chorus I've looked at numbers from both sides now From left and right and still somehow It's numbers' illusions I recall I really don't know numbers at all Secants, tangents, arc-cosines It seems like just a game sometimes What's my number, what's my line? I've looked at trig that way. Now all my graphs have gone awry I've lost the will to find out why Perhaps they'll make more sense by 'n' by But who am I to say? chorus I've looked at trig from both sides now From up and down and still somehow It's trig's illusions I recall I really don't know trig at all Edited 5/9/2016 Written 7/14/1986
