ntegration noun form, the value of the
integral is the last value that does not fail (or a pure noun form if
all methods fail).

<p>When the function <code>abs_integrate_use_if</code> is successful, it returns
a conditional expression; for example
</p><table><tr><td>&nbsp;</td><td><pre class="example"> (%i2) integrate(1/(1 + abs(x+1) + abs(x-1)),x);
 (%o2) %if(-(x+1)&gt;0,-log(1-2*x)/2+log(3)-2/3,%if(-(x-1)&gt;0,x/3+log(3)/2-1/3,log(2*x+1)/2))

 (%i3) integrate(exp(-abs(x-1) - abs(x)),x);
