Sandy,
You have to add java to the namespace, like so
xmlns:math="java.lang.Math" exclude-result-prefixes="math"

I just tried your code, and I got this exception :
javax.xml.transform.TransformerException: Prefix must resolve to a namespace: math
hope you can help me more

We use SVG to generate our Pie Charts and our bar charts. It's not too hard
to create. I looked at the code from this site and started creating my own
variations for testing.
http://www.svgopen.org/2003/papers/ CreatingSVGPieChartsThroughWebService
Here is a Pie Chart that I tested with: <fo:table-cell
xsl:use-attribute-sets="table-piechart-style"> <xsl:variable name="number"
select="operatingaverages/monthly/efficiency" /> <xsl:variable
name="difference" select="100 - $number" /> <xsl:variable
name="currentAngle" select="math:toRadians(($number div 100) * 360.0)" />
<xsl:variable name="halfAngle" select="math:toRadians((($number div 2) div
$total) * 360.0)" /> <xsl:variable name="rotation" select="270 + (360.0 *
($number div 100))" /> <xsl:variable name="x1" select="math:cos($halfAngle)
* 70" /> <xsl:variable name="y1" select="math:sin($halfAngle) * 70" />
<xsl:variable name="cosTheta" select="math:cos(math:toRadians($rotation))"
/> <xsl:variable name="sinTheta"
select="math:sin(math:toRadians($rotation))" /> <fo:instream-foreign-object>
<svg height="100" viewBox="0 0 200 100" width="200"
xmlns="http://www.w3.org/2000/svg";
xmlns:xlink="http://www.w3.org/1999/xlink";> <g> <path
style="fill:{$color1};stroke:black;stroke-width:1;fillrule:evenodd;
stroke-linejoin:bevel;"> <xsl:attribute name="transform">
<xsl:text>translate(100,50)</xsl:text> <xsl:text>rotate(</xsl:text>
<xsl:value-of select="$rotation" /> <xsl:text>)</xsl:text> </xsl:attribute>
<xsl:attribute name="d"> <xsl:text>M 50 0 A 50 50 0 </xsl:text> <xsl:choose>
<xsl:when test="$currentAngle > 3.14"> <xsl:text>1 </xsl:text> </xsl:when>
<xsl:otherwise> <xsl:text>0 </xsl:text> </xsl:otherwise> </xsl:choose>
<xsl:text>1 </xsl:text> <xsl:value-of select="math:cos($currentAngle) * 50"
/> <xsl:text> </xsl:text> <xsl:value-of select="math:sin($currentAngle) *
50" /> <xsl:text> L 0 0 Z</xsl:text> </xsl:attribute> </path> </g> </svg>
