在複數頭文件中定義了用於複數的tan()函數,此函數是tan()函數的複數版本。此函數用於計算複數z的複數tan。此函數返回複數z的tan。
用法:
tan(z);
參數:
- z:該方法采用代表複數的mandaory參數z。
返回值:此函數返回複數z的tan()。
以下示例程序旨在說明C++中的tan()函數:
計劃1:-
// C++ program to demonstrate
// example of tan() function.
#include <iostream>
#include <complex>
using namespace std;
int main ()
{
complex<double> complexnumber (0.0, 1.0);
// use of tan() function for complex number
cout << "The tan of " << complexnumber << " is "
<< tan(complexnumber) <<endl;
return 0;
}
輸出:
The tan of (0,1) is (0,0.761594)
計劃2:-
// C++ program to demonstrate
// example of tan() function.
#include <iostream>
#include <complex>
using namespace std;
int main ()
{
complex<double> complexnumber (1.0, 0.0);
// use of tan() function for complex number
cout << "The tan of " << complexnumber << " is "
<< tan(complexnumber) << endl;
return 0;
}
輸出:
The tan of (1,0) is (1.55741,0)
