OJ Brush question "seeking Sinh (x)"

Title Description

Write a function to find the value of Sinh (x), the approximate formula for Sinh (x) is Sinh (x) = (ex-e-X)/2, where a function is used to find the ex . The result retains two decimal places.

Input

X

Output

The value of the Sinh (x).

Sample input

1

Sample output

1.18

Tips

The main function is given below, and it is not required to include the following main function when committing

/* C code */

int main () {

Double X;

scanf ("%lf", &x);

printf ("%.2f\n", Udf_sinh (x));

return 0;

}

/* C + + code */

int main () {

Double X;

cin>>x;

Cout<<setiosflags (ios::fixed);

Cout<<setprecision (2);

Cout<<udf_sinh (x) <<endl;

return 0;

}

The code is as follows:

#include <iostream> #include <iomanip> #include <cmath>using namespace std;double Udf_sinh (double n) { Double Sinh; Sinh= (exp (n)-exp (-N))/2; return sinh;} int main () {double x;cin>>x;cout<<setiosflags (ios::fixed); cout<<setprecision (2); cout<<udf _sinh (x) <<endl;return 0;}

Operation Result:
