Trigonometry began
When Sine and Cos and Tan
[The latter, a perfect gentleman]
Agreed to work in a Triangle.
Now Sine was cross with Cos
Because she got into a tangle
With Cosec the Smart Alec,
Who had a special angle
For flirty Cotangent
[Also known as Cot]
Whose reputation
[Or shall we say, computation? ]
Was certainly not
Above board, like Tangent
[Also known as Tan,
Who, I repeat, was a perfect gentleman]
Cross-fighting in the Triangle,
They drew an obtuse angle;
And slowly by degrees
Sine began to freeze
Till one fine day,
Cosec ran away
With Cotangent...
Which left a place vacant
For the incorrigible Secant,
Who fought and fell out with Tangent…
In short,
Thanks to Cosec and Cot,
Trigonometry
Had to be abandoned.
