</span><span><span class="hljs-keyword">echo</span></span><span> </span><span><span class="hljs-string">"<p>在计算机编程或者数学应用中，我们经常需要求两个角度之间的差值。在 PHP 中，<code>asin()

</span></span><span><span>$sinA</span></span><span> = 0.5; // 对应角度 30°
</span><span><span>$sinB</span></span><span> = 0.86602540378; // 对应角度 60°

</span><span><span>$angleA</span></span><span> = rad2deg(asin(</span><span><span>$sinA</span></span><span>));
</span><span><span>$angleB</span></span><span> = rad2deg(asin(</span><span><span>$sinB</span></span><span>));

</span><span><span>$angleDifference</span></span><span> = abs(</span><span><span>$angleA</span></span><span> - </span><span><span>$angleB</span></span><span>);

echo '两个角度的差值为：' . </span><span><span>$angleDifference</span></span><span> . '°';

</span></span><span><span>$cosA</span></span><span> = 0.86602540378; // 对应角度 30°
</span><span><span>$cosB</span></span><span> = 0.5;           // 对应角度 60°

</span><span><span>$angleA</span></span><span> = rad2deg(acos(</span><span><span>$cosA</span></span><span>));
</span><span><span>$angleB</span></span><span> = rad2deg(acos(</span><span><span>$cosB</span></span><span>));

</span><span><span>$angleDifference</span></span><span> = abs(</span><span><span>$angleA</span></span><span> - </span><span><span>$angleB</span></span><span>);

echo '两个角度的差值为：' . </span><span><span>$angleDifference</span></span><span> . '°';
