arc cosecant
- noun
- /ɑrk koʊˈsiːkənt/
- Specialized
- Finding the arc cosecant of a value helps determine the original angle in trigonometric problems.
Examples
-
Can you calculate the arc cosecant of 2?
-
In advanced mathematics, the arc cosecant is often written as arccsc(x).
-
The calculator does not have a dedicated button for the arc cosecant function.
-
The arc cosecant function is essential in trigonometry.
-
To find the angle in a right triangle, you can use the arc cosecant of the opposite side's length divided by the hypotenuse.
-
In trigonometry, the arc cosecant function helps us determine angles when the cosecant value is known.
-
Most scientific calculators include the arc cosecant function for converting cosecant values back into angles.
Synonyms
An angle whose sine equals 1 divided by a given number
An angle whose cosecant equals a given number

Morphology
arc + cosecant
The phrase uses a conventional mathematical formation where 'arc' marks the inverse of a trigonometric function, so a learner who knows 'cosecant' and that 'arc' is used in math (e.g., arcsin, arccos) can infer the meaning. However, the ordinary sense of 'arc' (a curved line) does not transparently convey 'inverse function' to a general B1 learner, and the usage is domain-specific rather than following everyday compositional patterns.
Etymology
The term arc cosecant combines arc (a part of a circle that points to an angle) and cosecant (the number you get when you divide 1 by the sine). So arc cosecant means 'find the angle whose cosecant is a given number'.
