Answers to Questions
What does expand an expression means? (Definition)
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.
The concept of 'distributivity' is also important for developping: $ a \times (b + c) = (a \times b) + (a \times c) $
Example: $ (a+b)^2 $ is expanded $ a^2+2ab+b^2 $
How to develop a polynomial-like expression?
Developing a math expression (or a part of an equation) consists in expressing it in sum of factors (to eliminate the possible factorization) in order to obtain a longer writing but which can then make it possible to carry out simplifications.
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 $ 2\sin(x)\cos(x) $
