Math

math.js will also be available at https://github.com/aantthony/javascript-cas when and if it becomes large.

Structure

• Mathematical expressions are represented as an Array, where the elements are the arguments of the n-ary operator, and the operator is defined by the "type" property of the array. The elements are also mathematical expressions. So it is recursively defined until a string, or number is reached.

Operators

• summation is an n-ary operator. Inverse: minus each
• product is an n-ary operator.
• fraction is a binary operator.
• power is a binary operator.
• tetration is an n-ary operator. not necessary. Inverse: ?
• function is an n-ary operator. First element: string of function name. Other elements are arguments. This could be for example: log, sin, cos, W, or the "fact"orial function. Unless factorial should be separate.
• Minus (no eqtype) Expressed as multiplication by negative 1, or maybe: changing the sign of the first number in the array.

Methods

• .simplify()
• .differentiate()
• .integrate()
• .eval()

Solving

Inverse

Method

• alert(p("x+3*2").inverse())
