Evaluate 0 x e x d x. Notice how the limit declaration can include a subscript. You can buy it at hardware stores. A metal lath is a net of enmeshed metal.

As suggested in a comment the points sampled by tikz are spaced too far apart. A latex y way to handle this issue would be to define a macro called say floor using the declarepaireddelimiter device of the mathtools package. In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or. Left lfloor frac a b right rfloor left lceil frac c d right rceil.

A solid dot means including and an open dot means not including. Int limits 0 infty lfloor x rfloor e x dx. Floor and ceiling functions. Without this package rightarrow has to be used.

An open dot at y 1 so it does not include x 2 and a solid dot at y 2 which does include x 2. Definite integrals and sums involving the floor function are quite common in problems and applications. 0 x. The floor function is this curious step function like an infinite staircase.

At x 2 we meet. Attach a metal lath to a wooden floor. The best strategy is to break up the interval of integration or summation into pieces on which the floor function is constant. See the reference guide for a complete list of available operators.

The package amsmath is needed for the macro to. With such a setup you can pass an optional explicit sizing instruction big and bigg in the example code below or you can use the starred version of the macro floor to autosize the left and right hand brackets. Instead roll out and staple a metal lath over the entire floor first. Add a comment 3 answers active oldest votes.

The greatest integer function also known as the floor function gives the greatest integer less than or equal to its argument the floor of is usually denoted by or the action of this function is the same as rounding down on a positive argument this function is the same as dropping everything after the decimal point but this is not true for negative values.
