Math对象的asinh()函数接受一个数字,并以弧度返回其双曲线反正弦值。要将结果值转换为度数,请将其乘以180,然后将结果除以3.14159(pi值)。
它的语法如下
Math.asinh(0.5)

<script type="text/javascript">
var result = Math.asinh(90);
document.write("Hyperbolic arcsine value: "+result);
document.write("<br>");
document.write("Hyperbolic arcsine value in degrees: "+result*180/Math.PI);
</script>

Hyperbolic arcsine value: 5.192987713658941 Hyperbolic arcsine value in degrees: 297.53627905594817
