C++ <complex> - acosh() Function
The C++ <complex> acosh() function returns the complex inverse hyperbolic cosine of a complex number z. It is a function on complex plane, and has one branch cut, extending left from 1 along the real axis to -∞, continuous from above.
Mathematically, it can be expressed as:
Syntax
template<class T> complex<T> acosh (const complex<T>& z);
Parameters
z |
Specify the complex number. |
Return Value
Returns the complex inverse hyperbolic cosine of z.
Example:
The example below shows the usage of <complex> acosh() function.
#include <iostream> #include <complex> using namespace std; int main (){ complex<double> z1 (2, 2); complex<double> z2 (2, 0); complex<double> z3 (0, 2); //calculate the complex inverse hyperbolic cosine cout<<"acosh(z1): "<<acosh(z1)<<"\n"; cout<<"acosh(z2): "<<acosh(z2)<<"\n"; cout<<"acosh(z3): "<<acosh(z3)<<"\n"; return 0; }
The output of the above code will be:
acosh(z1): (1.73432,0.816547) acosh(z2): (1.31696,0) acosh(z3): (1.44364,1.5708)
