The sinh() is an inbuilt function in C++ STL which returns the hyperbolic sine of an angle given in radians.
Syntax :
sinh(data_type x)
Parameter :The function accepts one mandatory parameter x which specifies the hyperbolic angle in radian. The parameter can be of double, float or long double datatype.
Return Value: The function returns the hyperbolic sine of the argument. If the magnitude of the result is too large to be represented by a value of the return type, the function returns inf.
Program 1:
// C++ program to demonstrate the // sinh() function #include <bits/stdc++.h> using namespace std; int main() { double x = 4.1; double result = sinh(x); cout << "sinh(4.1) = " << result << endl; // x in Degrees double xDegrees = 90; x = xDegrees * 3.14159 / 180; result = sinh(x); cout << "sinh(90 degrees) = " << result << endl; return 0; } |
Output:
sinh(4.1) = 30.1619 sinh(90 degrees) = 2.3013
Program 2:
// C++ program to demonstrate the // sinh() function #include <bits/stdc++.h> using namespace std; int main() { int x = -4; double result = sinh(x); cout << "sinh(-4) = " << result << endl; // x in Degrees double xDegrees = 90; // convert to radians x = xDegrees * 3.14159 / 180; result = sinh(x); cout << "sinh(90 degrees) = " << result << endl; return 0; } |
Output:
sinh(-4) = -27.2899 sinh(90 degrees) = 1.1752
Errors and Exceptions: The function returns no matching function for call to error when a string or character is passed as an argument.
Below programs illustrate the errors and exceptions of sinh() method:
Program 3:
// C++ program to demonstrate the // sinh() function when a string is passed #include <bits/stdc++.h> using namespace std; int main() { string x = "gfg"; double result; result = sinh(x); cout << "sinh(x) = " << result << endl; return 0; } |
Output:
prog.cpp:14:20: error: no matching function for call to 'sinh(std::__cxx11::string&)' result = sinh(x);
Program 4:
// C++ program to demonstrate the sinh() // function When argument is too large #include <bits/stdc++.h> using namespace std; int main() { double x = 3000.0; double result = sinh(x); cout << "sinh(x) = " << result << endl; return 0; } |
Output:
sinh(3000.0) = inf
