# Expanding and Reducing Math Expression

## Trigonometric Expansion and Reduction

Tool to expand and reduce a mathematical expression (polynomial, fractions, equation, trigonometry, etc.

## Answers to Questions

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

The development allows expressing the polynomial in a addition of factors. The reduction is used to group each factor of the polynomial.

Example: $$(a+b)^2-2ab = a^2+2ab+b^2-2ab = a^2+b^2$$

### How to develop and reduce a fraction?

dCode offers dedicated tools for calculating fractions. The development consists of writing fractions to the same denominator and reducing is the simplification to the least common multiple.

### How to expand and reduce a trigonometric expression?

dCode can develop trigonometric expressions to simplify (reduce) their content (the goal is to reduce the content (between parenthesis) of the sine and cosine functions)

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