 points) to within a specified   generalized error tolerance, tolfun = max(abstol, reltol*| I |), i.e.,   | I - Q | &lt;= tolfun with confidence of at least 99%, where I is the   true integral value, Q is the estimated integral value, abstol is the   absolute error tolerance, and reltol is the relative error tolerance.   Usually the reltol determines the accuracy of the estimation; however,   if | I | is rather small, then abstol determines the accuracy of the   estimation.</p><p>It is recommended to use <b
