Nov 25, 2023 · I found trigonometric functions like versine, vercosine, haversine, exsecant, etc. But they are very simply related to the six basic trig functions.

Apr 17, 2019 · The versine (arguably the most basic of the functions), coversine, haversine and exsecant formulas had once been utilised for navigational purposes, prior to GPS tracking systems. However, recently, they have become less common in …

Jan 24, 2021 · Why are the trig functions versine, haversine, exsecant, etc, rarely used in modern mathematics? 1 Why does applying a small angle approximation to equivalent forms of $\frac{\cos^2 \theta}{\sin \theta\tan \theta}$ yield different results?

The second flattening, f ' = (a-b)/b, is the exsecant of the angle; The third flattening, f '' = (a-b)/(a+b), is the havertan (half of the versed tangent) of the angle; The second eccentricity, ε' = (a 2 -b 2 )/b 2 , is the tangent of the angle.

There are a lot of old trigonometric functions that fell out of popular use. For one, they can be expressed as linear combinations of the others. Also, they just didn't come up as much in investigations. Some others were versine, exsecant, and excosecant. $\endgroup$ –

Apr 4, 2021 · I was reading trigonometry functions and how they are defined for non acute angles in a unit circle. My question is that in the unit circle definition the sine of the ray is said to be it's y axis

Apr 27, 2017 · So far, I've proven the cases with radius and any other length; with any two of sine, versine or chord; with sine and cosine; with sine and tangent; with secant and tangent; with secant and exsecant, and with secant and cosecant. The co …

Jun 22, 2015 · There are four other reasonable possibilities which he could have meant: Inverse trigonometric functions, e.g. $\arcsin$, $\arccos$, $\arctan$, but these are no trigonometric functions.
