**Équations et inéquations**
1. **Equivalence of equations**: Two equations are equivalent if they have the same solution set.
Example: x + 2 = 3 and x + 2 – 2 = 3 + 2 are equivalent because they both equal x = 1.
2. **Symmetry**: An equation is symmetric if it remains unchanged when its variables are swapped.
Example: x^2 + y^2 = z^2 is a symmetric equation because swapping x and y does not change the equation.
3. **Transitivity**: If two equations are equivalent, then so are their solutions.
Example: x = 1 and x = 1 are equivalent, so their solution set {1} is also equivalent.
**Polynômes et fonctions**
1. **Addition of polynomials**: The sum of two polynomials is another polynomial with coefficients that are the sums of corresponding coefficients.
Example: (x + 2) + (x – 3) = 2x – 1
2. **Multiplication of polynomials**: The product of a polynomial and a monomial is another polynomial with coefficients that are the products of corresponding coefficients.
Example: x(x + 2) = x^2 + 2x
3. **Composition of functions**: The composition of two functions is another function that applies the first function to the input, then applies the second function to the output.
Example: f(x) = x^2 and g(x) = x + 1; then (f ∘ g)(x) = (x + 1)^2
**Algèbre linéaire et matrices**
1. **Linearity**: A linear transformation is a function that preserves addition and scalar multiplication.
Example: f(x) = 2x + 3 is a linear transformation because it satisfies the properties of linearity.
2. **Matrix operations**: Matrices can be added, subtracted, and multiplied using specific rules.
Example: adding two matrices [a b] and [c d] results in [a+c b+d]
3. **Determinants**: The determinant of a matrix is a scalar value that can be used to determine whether the matrix is invertible or not.
These are just some of the fundamental properties of algebra, but I hope this helps give you a sense of how they relate to each other! »
