Rewrite a logarithm

Properties 3 and 4 leads to a nice relationship between the logarithm and exponential function. This is a nice fact to remember on occasion.

To make the correspondence exact, an algorithm is given in terms of transformation rules that are applied to rewrite non-Strict MathML constructs into a strict equivalents. The individual rules are introduced in context throughout the chapter.

This means it has to give specific strict interpretations to some expressions whose meaning was insufficiently specified in MathML2. The intention of this algorithm is to be faithful to mathematical intuitions.

Supported differentiation rules

However edge cases may remain where the normative interpretation of the algorithm may break earlier intuitions. A conformant MathML processor need not implement this transformation.

The existence of these transformation rules does not imply that a system must treat equivalent expressions identically.

In particular systems may give different presentation renderings for expressions that the transformation rules imply are mathematically equivalent. The key to extensibility is the ability to define new functions and other symbols to expand the terrain of mathematical discourse.

To do this, two things are required: In MathML 3, the csymbol element provides the means to represent new symbols, while Content Dictionaries are the way in which mathematical semantics are described.

The association is accomplished via attributes of the csymbol element that point at a definition in a CD. Content Dictionaries are structured documents for the definition of mathematical concepts; see the OpenMath standard, [OpenMath].

To maximize modularity and reuse, a Content Dictionary typically contains a relatively small collection of definitions for closely related concepts.

There is a process for contributing privately developed CDs to the OpenMath Society repository to facilitate discovery and reuse. MathML 3 does not require CDs be publicly available, though in most situations the goals of semantic markup will be best served by referencing public CDs available to all user agents.

It is important to note, however, that this information is informative, and not normative. In general, the precise mathematical semantics of predefined symbols are not not fully specified by the MathML 3 Recommendation, and the only normative statements about symbol semantics are those present in the text of this chapter.

The semantic definitions provided by the OpenMath Content CDs are intended to be sufficient for most applications, and are generally compatible with the semantics specified for analogous constructs in the MathML 2.

However, in contexts where highly precise semantics are required e. These building blocks are combined using function applications and binding operators.

It is important to have a basic understanding of these key mathematical concepts, and how they are reflected in the design of Content MathML.

For the convenience of the reader, these concepts are reviewed here. It may have other properties, such as being an integer, but its value is not a fixed property. By contrast, the plus sign is an identifier that represents a fixed and externally defined object, namely the addition function.

Such an identifier is termed a symbol, to distinguish it from a variable. Common elementary functions and operators all have fixed, external definitions, and are hence symbols. Content MathML uses the ci element to represent variables, and the csymbol to represent symbols.

The most fundamental way in which symbols and variables are combined is function application. Content MathML makes a crucial semantic distinction between a function itself a symbol such as the sine function, or a variable such as f and the result of applying the function to arguments.

The apply element groups the function with its arguments syntactically, and represents the expression resulting from applying that function to its arguments. Mathematically, variables are divided into bound and free variables.

Bound variables are variables that are assigned a special role by a binding operator within a certain scope.The Intent of Content Markup The intent of Content Markup is to provide an explicit encoding of the underlying mathematical meaning of an expression, rather than any particular rendering for the expression.

Mathematics is distinguished both by its use of rigorous formal logic to define and analyze mathematical concepts, and by the use of a (relatively) formal notational system to. Integration- the basics Dr. Mundeep Gill Brunel University 1 Integration Integration is used to find areas under curves.

Integration is the reversal of differentiation hence functions can be integrated. Back to basics. A long time ago (in a galaxy far, far away.), developers had to know exactly the number of operations they were coding.

They knew by heart their algorithms and data structures because they couldn’t afford to waste the CPU and memory of their slow computers.
