NSum

FilledSmallSquare NSum[f, {i, imin, imax}] gives a numerical approximation to the sum .

FilledSmallSquare NSum[f, {i, imin, imax, di}] uses a step di in the sum.

FilledSmallSquare NSum can be used for sums with both finite and infinite limits.

FilledSmallSquare NSum[f, {i, ... }, {j, ... }, ... ] can be used to evaluate multidimensional sums.

FilledSmallSquare NSum[f, {i, imin, imax}] can be entered as .

FilledSmallSquare can be entered as AliasIndicatorsumAliasIndicator or \[Sum].
