MedCalcACSC function
Inverse cosecant function. ACSC(x) returns the inverse cosecant of x. The inverse cosecant function is the inverse function of the cosecant function and calculates the angle for a given cosecant. x must satisfy |x| ≥ 1 (i.e. x ≤ −1 or x ≥ 1). The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function.
The argument x can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the ACSC function applied to all elements.
The inverse cosecant can be expressed in terms of the ASIN function:
$$ \operatorname{acsc}(x) = \operatorname{asin}\!\left(\frac{1}{x}\right) $$
Examples
ACSC(1) equals 1.5707963 (=PI/2)
ACSC(−1) equals −1.5707963 (=−PI/2)
ACSC(2) equals 0.5235988 (=PI/6)
DEGREES(ACSC(2)) equals 30
