# Math Expression Expansion

## Trigonometric Expression Expansion

Tool to realize the development of a mathematical expression (polynomial, product, ...) it is the reverse factoring process, and it create an expanded form.

### How to develop a polynomial-like expression?

dCode can expand and reduce mathematical expression (a part of an equation) in order to express it in sum of factors.

Example: (a+b)^2 gives a^2+2ab+b^2

The development consists of the transformation of a multiplication or a mathematical product into a sum or a difference. The expansion is also called a development (eg. for a polynom).

To achieve the operations, dCode uses the distributive property of multiplication over addition and subtraction.

After expansion, dCode automatically calculates the reduced form of the expression

### How to expand a trigonometric expression?

dCode expands trigonometric expressions (functions sinus, cosinus, etc.) in order to simplify their content

Example: sin(2x) gives 2sin(x)cos(x)
