	<title>삼각 함수</title>
    
    <p>삼각 함수 계산은 sin, cos, tan <link xref="function">함수</link>로 처리할 수 있습니다.</p>
    <example>
    <p>sin 45</p>
    </example>
    <p>
    To change the angle units used, use one of the following methods:
    </p>
    <list>
    <item><p>Press the menu button in the top-right
    corner of the window and select <gui style="menuitem">Preferences</gui></p></item>
    <item><p>In <gui>advanced mode</gui> you can use the Rad/Grad/Deg toggle button
    to toggle between units</p></item>
    </list>
    <p>
    Trigonometry buttons are visible when in <link xref="mouse">Advanced mode</link>.
    </p>
    <p>함수 뒤에 "h"를 붙이면 하이퍼볼릭 함수가 됩니다.</p>
    <example>
    <p>sinh 0.34</p>
    </example>
    <p>반전 함수는 ⁻¹ 반전 기호(<keyseq><key>Ctrl</key><key>I</key></keyseq>) 또는 함수의 "a" 형식(아크 삼각함수)으로 입력할 수 있습니다. 다음 두 수식은 동일합니다.</p>
    <example>
    <p>sin⁻¹ 0.5</p>
    <p>asin 0.5</p>
    </example>   
    <p><link xref="variable">π</link>를 키보드로 입력하려면 <keyseq><key>Ctrl</key><key>P</key></keyseq>키를 사용하십시오.</p>
