acscd

Inverse cosecant in degrees

Syntax

Y = acscd(X)

Description

Y = acscd(X) returns the inverse cosecant (cosec^-1) of the elements of X in degrees. The function accepts both real and complex inputs.

• For real values of X in the intervals [-∞, -1] and [1, ∞], acscd(X) returns values in the range [-90, 90].

• For real values of X in the interval (-1, 1) and for complex values of X, acscd(X) returns complex values.

Examples

Inverse Cosecant of Vector

x = [20 10 Inf];
y = acscd(x)

y = 1×3

    2.8660    5.7392         0

The acscd operation is element-wise when you pass a vector, matrix, or N-D array.

Inverse Cosecant of Complex Value

acscd(1+i)

ans = 
25.9136 -30.4033i

Input Arguments

X — Cosecant of angle

scalar value | vector | matrix | multidimensional array | table | timetable

Cosecant of angle, specified as a real-valued or complex-valued scalar, vector, matrix, multidimensional array, table, or timetable. The acscd operation is element-wise when X is non-scalar.

Data Types: single | double | table | timetable
Complex Number Support: Yes

Output Arguments

Y — Angle in degrees

scalar value | vector | matrix | multidimensional array | table | timetable

Angle in degrees, returned as a real-valued or complex-valued scalar, vector, matrix, multidimensional array, table, or timetable of the same size as X.

Version History

Introduced before R2006a

R2023a: Perform calculations directly on tables and timetables

The acscd function can calculate on all variables within a table or timetable without indexing to access those variables. All variables must have data types that support the calculation. For more information, see Direct Calculations on Tables and Timetables.
