      <content:encoded><![CDATA[<p>From the <a href="https://write.as" rel="nofollow">write.as</a> or <a href="https://writefreely.org" rel="nofollow">writefreely</a> blog&#39;s Customize page, there is a checkbox for <a href="https://www.mathjax.org/" rel="nofollow">MathJax</a> support.</p>

<p>An example $\int_0^\infty e^{-x^2} dx=\frac{\sqrt{\pi}}{2}$ of an inline equation.</p>

<p>$\Lambda$CDM</p>

<p>$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$</p>

<p>$\cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ)$
</p>

<p>Block mode is also supported:
$$\cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ)$$</p>

<p>When $a \ne 0$, there are two solutions to (ax^2 + bx + c = 0) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$</p>
