Answer link. When we have 90°, "Cosec" will become "sec". Because there are no maximum or minimum values of a tangent function, the term amplitude cannot be interpreted as it is for the sine and cosine functions.
The cosecant function is the reciprocal of the sine function, which means that the cosecant of a negative angle will be interpreted as csc (− θ) = 1 sin (− θ) = 1 − sin θ = − csc θ. Therefore, you can find the missing terms using nothing else but our ratio calculator! Trigonometry has plenty of applications: from everyday life problems such as calculating the height or distance between objects to the satellite navigation system, astronomy, and geography.. We know that sin x is 0 at integral multiples of π, hence the domain and range of cosecant are given by: Domain = R - nπ; Range = (-∞, -1] U [1, ∞) The range of cosecant can be derived exactly the same way how we derived for secant.
