# Expanding and Reducing Math Expression

## Trigonometric Expansion and Reduction

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

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

The development allows expressing the polynomial in a addition (sum) or subtraction (difference) of factors. The reduction is used to group each factor of the polynomial or simplify the result.

Example: $(a+b)^2-2ab$ can be expanded $a^2+2ab+b^2-2ab$ and then be reduced $a^2+b^2$

The development and reduction operations is a basic maths calculation in middle school.

### 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 $2\sin{x}\cos{x}$
