What was versine used for?
The versine or versed sine is a trigonometric function found in some of the earliest (Vedic Aryabhatia I) trigonometric tables. The versine of an angle is 1 minus its cosine. There are several related functions, most notably the coversine and haversine.
What is Versx?
– the versine or versed sine is defined as: versin(x) or vers(x) = 1 – cos(x) – the vercosine or versed cosine is defined as: vercosin(x) = 1 + cos(x) – the coversine or coversed sine is defined as: coversin(x) = 1 – sin(x)
Are there more than 6 trig functions?
The most popular answer to the number of basic trig functions may be six. Unlike calculator designers, calculus textbook authors find the cosecant, secant, and cotangent functions sufficiently useful to justify their inclusion as first-class trig functions.
What is Ver sin theta?
The versine or versed sine is a trigonometric function already appearing in some of the earliest trigonometric tables. The versine of an angle equals 1 minus its cosine. There are several related functions, most notably the coversine and haversine. 1jaiz4 and 16 more users found this answer helpful. Thanks 9.
Can there be 8 trigonometric ratios?
(It’s well known that you can shake a stick at a maximum of 8 trig functions.) The familiar sine, cosine, and tangent are in red, blue, and, well, tan, respectively. They’re all just simple combinations of dear old sine and cosine.
What is secant function?
Secant Definition The secant function is a periodic function in trigonometry. The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle.
What does SEC mean in maths?
In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec(θ) = hypotenuse / adjacent. It is not commonly used, and is equal to 1/cosine.
What is cosec in math?
Cosecant is one of the six trigonometric ratios which is also denoted as cosec or csc. The cosecant formula is given by the length of the hypotenuse divided by the length of the opposite side in a right triangle.
What is Exsecant used for?
They used to be important in fields such as surveying, railway engineering, civil engineering, astronomy, and spherical trigonometry and could help improve accuracy, but are rarely used today except to simplify some calculations.
What are the 12 trigonometric ratios?
| Trigonometric Ratios | |
|---|---|
| Sin θ | Opposite Side to θ/Hypotenuse |
| Cot θ | Adjacent Side/Opposite Side & 1/tan θ |
| Sec θ | Hypotenuse/Adjacent Side & 1/cos θ |
| Cosec θ | Hypotenuse/Opposite Side & 1/sin θ |
How many trigonometry are there?
The trigonometric identities hold true only for the right-angle triangle. All the trigonometric identities are based on the six trigonometric ratios. They are sine, cosine, tangent, cosecant, secant, and cotangent.
