NSum

  • NSum[ f , { i , imin , imax } ] gives a numerical approximation to the sum .
  • NSum[ f , { i , imin , imax , di } ] uses a step di in the sum.
  • NSum can be used for sums with both finite and infinite limits.
  • NSum[ f , { i , ... } , { j , ... } , ... ] can be used to evaluate multidimensional sums.
  • NSum[ f , { i , imin , imax } ] can be entered as .
  • can be entered as sum or \ [Sum] .
  • See also: NProduct .
