Answers to Questions

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 is expanded 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 development is also called an expansion and the technique is called a polynomial expansion.

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

After expansion, dCode calculator automatically computes the reduced form of the math expression

How to expand a trigonometric expression?

dCode expands algebraic expressions but also trigonometric expressions (functions sine, cosine, etc.) in order to simplify their content

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