std::asin(std::complex) (3) - Linux Man Pages
Defined in header <complex>
template< class T > (since C++11)
complex<T> asin( const complex<T>& z );
Computes complex arc sine of a complex value z. Branch cut exists outside the interval [−1 ; +1] along the real axis.
z - complex value
If no errors occur, complex arc sine of z is returned, in the range of a strip unbounded along the imaginary axis and in the interval [−π/2; +π/2] along the real axis.
Errors and special cases are handled as if the operation is implemented by -i * std::asinh(i*z), where i is the imaginary unit.
Inverse sine (or arc sine) is a multivalued function and requires a branch cut on the complex plane. The branch cut is conventionally placed at the line segments (-∞,-1) and (1,∞) of the real axis.
The mathematical definition of the principal value of arc sine is asin z = -iln(iz +
For any z, asin(z) = acos(-z) -
