Description

It returns a valarray containing the hyperbolic sines of all the elements of x, in the same order.

Declaration

Following is the declaration for std::sinh function.

```template<class T> valarray<T> sinh (const valarray<T>& x);
```

C++11

```template<class T> valarray<T> sinh (const valarray<T>& x);
```

Parameters

x − It is containing elements of a type for which the unary function abs is defined.

Return Value

It returns a valarray containing the hyperbolic sines of all the elements of x, in the same order.

Exceptions

Basic guarantee − if any operation performed on the elements throws an exception.

Data races

All elements effectively copied are accessed.

Example

In below example explains about std::sinh function.

```#include <iostream>
#include <cstddef>
#include <cmath>
#include <valarray>

int main () {
double val[] = {0.3, 1.2, 3.5};
std::valarray<double> foo (val,3);

std::valarray<double> bar = sinh (foo);

std::cout << "foo:";
for (std::size_t i=0; i<foo.size(); ++i)
std::cout << ' ' << foo[i];
std::cout << '\n';

std::cout << "bar: ";
for (std::size_t i=0; i<bar.size(); ++i)
std::cout << ' ' << bar[i];
std::cout << '\n';

return 0;
}
```

Let us compile and run the above program, this will produce the following result −

```foo: 0.3 1.2 3.5
bar:  0.30452 1.50946 16.5426
```
