**Équations et inéquations**
* Reflexivity: An equation is reflexive if it remains true when we replace each variable with its own value.
* Symmetry: An equation is symmetric if it remains true when we swap the two variables being compared.
* Transitivity: An equation is transitive if it remains true when we chain together multiple equations.
Example: 2x + 3 = 5 and x = 2 are reflexive, symmetric, and transitive because replacing x with its own value (2) in the first equation yields a true statement.
**Polynômes et fonctions**
* Homogeneity: A polynomial function is homogeneous if it remains unchanged when we multiply each variable by a constant.
* Additivity: A polynomial function is additive if the sum of two functions is also a polynomial function.
* Multiplicativity: A polynomial function is multiplicative if the product of two functions is also a polynomial function.
Example: The function f(x) = x^2 is homogeneous because f(3x) = (3x)^2 = 9x^2. It’s additive and multiplicative because (f(x) + f(y)) = (x^2 + y^2) is still a polynomial function, and (f(x) * f(y)) = (x^2 * y^2) is also a polynomial function.
**Algèbre linéaire et matrices**
* Commutativity: In linear algebra, matrix multiplication is not commutative. However, addition of matrices is commutative.
* Associativity: Matrix multiplication is associative, meaning that the order in which we multiply matrices doesn’t change the result.
* Distributivity: The distributive property holds for linear combinations of matrices.
Example: The matrices A and B are not commutative because AB ≠ BA. However, A + B = B + A, and (A * C) * D = A * (C * D).
These properties help us understand the behavior of equations, polynomials, and matrices in algebra. They provide a foundation for solving problems and modeling real-world phenomena. »
