COSEC(x)
- where x is in Radians
- by default Calci use Radian as angle
COSEC can be used if the angle is in degrees.
The angle can be a single value or any complex array of values.
For example COSEC(1..100) can give an array of the results, which is the COSEC value for each of the elements in the array. The array could be of any shape.
Description
Consider x = 90 then =COSEC(RADIANS(90)) gives 1
- This function gives the cosecant of angle 'x'.
- This function is the reciprocal of SIN function. i.e.,cosec(x)=1/sin(x).
- In a right angled triangle cosec(x)=hypotenuse/opposite side.
- Here x is in radians.
- To convert a degree value to radian, multiply 'x' with PI()/180 or use the radians function RADIANS(X). This function is also denoted by CSC(x)
The following example shows how COSEC is applied to an array of numbers containing numbers 1..10.
