Prototype
template<class Tnum>
interval<Tnum> asin(const interval<Tnum>& x) ;
Description
Computes the arcsine of an interval. If the lower bound of the interval is less than -1.0 or the upper bound is greater than 1.0, it will print to std error :
`ArcSin argument out of range`
and will return NaN
``` asin(x) = [asin(inf(x)),asin(sup(x))]
```

Example
In mathfunc.cc:
```  cout << "A:" << A << endl << endl;
cout << "Square     :" << sqr(A) << endl;
cout << "Square Root:" << sqrt(A) << endl;
cout << "Tangent    :" << tan(A) << endl;
cout << "ArcTangent :" << atan(A) << endl;
cout << "Sine       :" << sin(A) << endl;
cout << "Cosine     :" << cos(A) << endl;
cout << "Arcsine    :" << asin(A) << endl;
cout << "Arcosine   :" << acos(A) << endl;
cout << "Log        :" << log(A) << endl;
cout << "Ln         :" << ln(A) << endl;
cout << "Power (A^A):" << pow(A,A) << endl;
cout << "Exponent   :" << exp(A) << endl;
