    <p>
      Use Euler's method with <m>h=<xsl:value-of select="h"/></m> to approximate
      <m>x(<xsl:value-of select="final/t"/>)</m> and <m>y(<xsl:value-of select="final/t"/>)</m> given the following
      system of IVPs.

    <me>
        x'=<xsl:value-of select="xp"/>\hspace{2em}
        x(<xsl:value-of select="init/t"/>)=<xsl:value-of select="init/x"/>
