list ln log lowlimit lt

lambda

Syntax

<lambda>(variable) + <apply>definition</apply></lambda>

Description

The lambda element represents the definition of a lambda function. A lambda function with n arguments is represented as a lambda element with n + 1 child elements. The first n elements are the arguments, each enclosed in a bvar element, and the last child element is the definition of the function, typically specified using an apply element.

Attributes

This element accepts the attributes definitionURL and encoding.

laplacian

Syntax

<apply><laplacian /> function</apply>

Description

The laplacian element represents the Laplacian operator of vector calculus.

Attributes

This element accepts the attributes definitionURL and encoding.

lcm

Syntax

<apply><lcm /> (number)*</apply>

Description

The lcm element represents the lowest common multiple of a set of integers, specified as arguments.

Attributes

This element accepts the attributes definitionURL and encoding.

leq

Syntax

<apply><leq /> arg1 arg2</apply>

Description

The leq element is used to indicate that one element is less than or equal to another. It can take two or more arguments.

Attributes

This element accepts the attributes definitionURL and encoding.

limit

Syntax

<apply><limit /> variable limit function</apply>

Description

The limit element represents the operator for the limit of a sequence or function. You can specify the limit point either by using a pair of bvar and lowlimit elements or by using a condition element.

Attributes

This element accepts the attributes definitionURL and encoding.

list

Syntax

<list>elements</list>

or

<list>
  (<bvar> ... </bvar>)*
  <condition> ... </condition>
</list>

Description

The list element is used to represent a set of elements. The elements can either be specified explicitly or by using bvar and condition elements. This element is similar to the set element, the only difference being that in a list, the order of elements is relevant.

Attributes

This element accepts the attributes definitionURL and encoding. In addition, it accepts the attribute shown in the following table.

Table: Attribute of list.

Name	Values	Default
order	lexicographic | numeric	lexicographic

The order attribute specifies the criterion used for ordering the elements of the list. With the setting lexicographic, the elements are ordered alphabetically; with the setting numeric, the elements are ordered numerically.

ln

Syntax

<apply><ln /> arg</apply>

Description

The ln element represents the natural logarithmic function.

Attributes

This element accepts the attributes definitionURL and encoding.

log

Syntax

<apply><log /> arg</apply>

Description

The log element represents the logarithm function.

Attributes

This element accepts the attributes definitionURL and encoding.

lowlimit

Syntax

<lowlimit>limit</lowlimit>

Description

The lowlimit element is a qualifier element that is used in conjunction with the int element to represent the lower limit of a definite integral.

Attributes

This element accepts the attributes definitionURL and encoding.

lt

Syntax

<apply><lt /> arg1 arg2</apply>

Description

The lt element is used to indicate that one element is less than another. It can take two or more arguments.

Attributes

This element accepts the attributes definitionURL and encoding.
