<h1>数学函数 - sinh</h1>
|
||
|
||
|
||
<p>原型:extern float sinh(float x);</p>
|
||
|
||
<p>用法:#include <math.h></p>
|
||
|
||
<p>功能:计算x(弧度表示)的双曲正弦值。</p>
|
||
|
||
<p>说明:sinh(x)=(e^x-e^(-x))/2。</p>
|
||
|
||
举例:<pre><code class="language-c">
|
||
|
||
|
||
// sinh.c
|
||
|
||
#include <syslib.h>
|
||
#include <math.h>
|
||
|
||
main()
|
||
{
|
||
float x;
|
||
|
||
clrscr(); // clear screen
|
||
textmode(0x00); // 6 lines per LCD screen
|
||
|
||
x=PI/4.;
|
||
printf("sinh(%.4f)=%.4f\n",x,sinh(x));
|
||
|
||
getchar();
|
||
return 0;
|
||
}
