What Is the Sign- Mathematics

My pencil's lead taps the paper, My mind confused and in a mess, It seems I'm searching for an answer, That basic math, will not assess, No! This is calc. Trigonometric function, Yet my mind beckons sociology, Perhaps the answer lays in psych, Or even logistics possibly, The question, What is the sin(x)? Has an annunciation that leaves me bewildered, It seems my mind has wondered off, Because a text was just delivered, From my ex, nontheless, A man with the power to misconstrue, All the principles of math, And gravitational laws that apply to you, What is the sign of ex?, (sin(x)) Well my ex is but a man, So when x is one, it seems there is none, For the answer is merely zero, Zero, I scribble with my hand, Generally speaking the sin(x) is y, I wonder why he didn't call back, The sign from my ex that did perplex, Was why he couldn't say goodbye.
