Enter any angle or radian to calculate the corresponding cosecant value.
The cosecant function (
In a right triangle, the cosecant of an angle
On the unit circle, the cosecant of an angle
Consider a right triangle where one angle is
Solution:
Using the definition of cosecant:
Thus, the cosecant of
Suppose you are calculating the slope of a hill with an angle of
Solution:
Using the definition of cosecant:
Thus, the cosecant of
The graph of the cosecant function exhibits periodic behavior and features vertical asymptotes. Below are some key properties:
The sign and behavior of cosecant in different quadrants are as follows:
Quadrant | Degrees | Radians | Sign | Range | Monotonicity |
---|---|---|---|---|---|
1st Quadrant | Positive | Decreasing | |||
2nd Quadrant | Positive | Increasing | |||
3rd Quadrant | Negative | Increasing | |||
4th Quadrant | Negative | Decreasing |
The reciprocal of the cosecant function is the sine function (
The derivative of the cosecant function is:
The integral of the cosecant function is:
The inverse cosecant function (
