<h1>数学函数 - sinh</h1>
<p>原型：extern float sinh(float x);</p>
<p>用法：#include &lt;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 &lt;syslib.h>
#include &lt;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;
}
</code></pre>相关函数：<a href="cosh.html">cosh</a>,<a href="tanh.html">tanh</a>
