The Origins of Trigonometry: AULD LANG's SINE

POST #66
ORIGINAL SONG: "Auld Lang Syne", by Robert Burns, 1788.
Robert Burns
PARODY COMPOSED: Giorgio Coniglio, January, 2015.

KEYWORDS: traditional, math-and-science, multicultural


(to the tune of "Auld Lang Syne")

A clever Scot, Auld Simon Lang
Rests in a box o’ pine;
His contributions near-forgot -
‘E invented Auld Lang’s Sine.

Dreamed up the trig’s big Sine, and its
Gude cos’n bright an’ fine;
[One minus (Lang’s-Sine)squared], my dear,
Its square-root – Auld Lang’s Cosine.

And though his mind did grow less clear,   
His concept’s been refined –
One o’er t’other – Tangent, dear
Derived frae Auld Lang’s Sine.

And at the end, his sight grown dim
Ideas still implant –
Turned on its head, Auld Lang’s Cosine,
We know as Auld Lang’s Secant.

His final word, “Cotangent”,
Then his soul was carried up;
So kindly pass the pi, my dear,
And to Lang we’ll drink a cup.

  1. In mathematics, the trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others. You need a lot of practice to learn trigonometry. Your basics should be clear. You can also take the help of online applications and websites for more preparation.Trigonometry equations are always difficult to solve. Because you can not learn and perform this type of equations at first attempt. From childhood, trigonometry was the only subject that scared me when I sit in the exams.
