asin

Inverse sine in radians

Usage

asin(A)

• A should be an array, which can be real or complex.
• It returns an array containing the inverse sine (in radians) of each element of A.
• For real elements of A lying in $[-1,1]$​, it returns values in $[-\frac{\pi}{2},\frac{\pi}{2}]$​​. (See example below.)
• For real elements of A having absolute value $>1$, it returns complex numbers.
• The output has the same size as A.

Example

Input

x = linspace(-1,1);
y = asin(x);
plot(x,y,'.-');
xlabel('x')
ylabel('asin(x)')
