CSC

csc(expr)

Description

The cosecant function csc is used to calculate the cosecant value of a given angle expr. The cosecant function is the reciprocal of the sine function, i.e., csc(x) = 1/sin(x). This function is widely used in fields such as mathematics, physics, and engineering.

Parameter Description

• expr (type double): The angle value for which the cosecant value needs to be calculated, in radians.

Return Result

The return type is double, representing the calculated cosecant value.

Usage Example

1. Calculate the cosecant value for an angle of 1 radian:

SELECT csc(1);

Results:

1.1883951057781212

2. Calculate the cosecant value for an angle of π/2 radians (90°):

SELECT csc(PI()/2);

Results:

1.0

Notes

• When the expr parameter value is 0, the result of the cosecant function is infinity (Infinity).
• The cosecant function only accepts angle values in radians. To convert degrees to radians, use the radians() function.
