ifies to a
non-signum expression on each subinterval; for example
</p><table><tr><td>&nbsp;</td><td><pre class="example"> (%i1) integrate(1 / (1 + abs(x-5)),x,-5,6);
 (%o1) log(11)+log(2)
</pre></td></tr></table>

<p>Finally, <code>abs_integrate</code> is able to determine antiderivatives of <em>some</em>
functions of the form <em>F(x, |x - a|)</em>; examples
</p><table><tr><td>&nbsp;</td><td><pre class="example"> (%i2) integrate(1/(1 + abs(x)),x);
 (%o2) ((signum(x)+1)*log(x+1))/2-(log(1-x)*(1-signum(x)))/
