Definition:Cosecant

Linguistic Note
Like secant, the word cosecant comes from the Latin secantus that which is cutting, the present participle of secare to cut.

The co- prefix, as with similar trigonometric functions, is a reference to complementary angle: see Cosecant is Secant of Complement.

It is pronounced with an equal emphasis on both the first and second syllables: co-see-kant.
