alphabet">Greek alphabet</a>. It was used before the alphabet converted its classical standard form. It looked like a Latin "F", but it was pronounced like "w". In the 5th century BC, people stopped using it because they could no longer pronounce the sound "w" in Greek. However, they kept it as a sign for the number "6" in the system of <a href="/wiki/Greek_numerals" title="Greek numerals">Greek numerals</a>. It was originally called "Wau" because of its sound. Later, when the sound was lost, it was called "Digamma", which means "double <a href="/wiki/Gamma" title="Gamma">Gamma</a>", because it looks like a Gamma (Γ) with two hooks. The Latin letter <a href="/wiki/F" title="F">F</a> was also taken over from Wau. </p><p>In <a href="/wiki/Mathematics" title="Mathematics">mathematics</a>, the name "digamma" is used in <a href="/w/index.php?title=Digamma_function&action=edit&redlink=1" class="new" title="Digamma function (not yet started)">digamma function</a>, which is the <a href="/wiki/Derivative_(mathematics)" title="Derivative (mathematics)">derivative</a> of the <a href="/wiki/Logarithm" title="Logarithm">logarithm</a> of <a href="/wiki/Gamma_function" title="Gamma function">gamma function</a> (that is, <span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle (\ln \Gamma (z))'}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mo stretchy="false">(</mo> <mi>ln</mi> <mo>⁡<!-- --></mo> <mi mathvariant="normal">Γ<!-- Γ --></mi> <mo stretchy="false">(</mo> <mi>z</mi> <mo stretchy="false">)</mo> <msup> <mo stretchy="false">)</mo> <mo>′</mo> </msup> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle (\ln \Gamma (z))'}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/0aedca46cae514b0aebd27469efd34bfcda5674a" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.838ex;
