Main Content

Syntax

Description

`Y` = asin([X](#mw%5F52cb89d0-23d9-4f6d-a7cd-69183f958101)) returns theInverse Sine (sin-1) of the elements of X in radians. The function accepts both real and complex inputs.

Find the inverse sine of a value.

Find the inverse sine of the elements of vector x. The asin function acts on x element-wise.

x = [0.5i 1+3i -2.2+i]; y = asin(x)

y = 1×3 complex

0.0000 + 0.4812i 0.3076 + 1.8642i -1.1091 + 1.5480i

Plot the inverse sine function over the intervals -1≤x≤1.

x = -1:.01:1; plot(x,asin(x)) grid on

Sine of angle, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. The asin operation is element-wise whenX is nonscalar.

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