check if the vectors are linearly independent?
63734
We have now found a test for determining whether a given set of vectors is linearly independent: A set of n vectors of length n is linearly independent if the matrix with these vectors as columns has a non-zero determinant. The set is of course dependent if the determinant is zero.

(1) T is one-to-one if and only if the columns of A are linearly independent, which happens precisely when A has a pivot position in every column. (2) T is onto if and only if the span of the columns of A is Rm, which happens precisely when A has a pivot position in every row.

Then f(π/2) = 2(1)(−1) − 0 = −2, so sin x and sin2x are linearly independent. ... So the Wronskian does not tell us whether the functions are linearly dependent or independent. Since the Wronskian is 0, let us first try to show that the functions are linearly dependent. We can get −2x2 from f by multiplying by −2.

Just use abs(x - y) . This'll return the net difference between the two as a positive value, regardless of which value is larger. Please share simpler or more pythonic approaches, if you have one.

Linear Combination of Vectors. If one vector is equal to the sum of scalar multiples of other vectors, it is said to be a linear combination of the other vectors. For example, suppose a = 2b + 3c, as shown below. Note that 2b is a scalar multiple and 3c is a scalar multiple.

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept.

Manhattan: Take the sum of the absolute values of the differences of the coordinates. |a−c|+|b−d|. For your vectors, it's the same thing except you have more coordinates.

In the theory of vector spaces, a set of vectors is said to be linearly dependent if at least one of the vectors in the set can be defined as a linear combination of the others; if no vector in the set can be written in this way, then the vectors are said to be linearly independent.

A basis is called an orthonormal basis if it is a basis which is orthonormal. For an orthonormal basis, the matrix with entries Aij = vi · vj is the unit matrix. Orthogonal vectors are linearly independent. A set of n orthogonal vectors in Rn automatically form a basis.

A vector v∈V∖{0} is called a generalized eigenvector to an eigenvalue λ∈C of T iff there exists k>0 such that (λI−T)kv=0. From the generalized eigenspace decomposition it follows that generalized eigenvectors to different eigenvalues are linearly independent. hence a1=0, and a2=0.

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept. It is the value of the dependent variable when x = 0.

Note that the result for the length of the cross product leads directly to the fact that two vectors are parallel if and only if their cross product is the zero vector. This is true since two vectors are parallel if and only if the angle between them is 0 degrees (or 180 degrees).

Vector is equal to vector b. For two vectors to be equal, they must have both the magnitude and the directions equal.

For homogeneous systems this happens precisely when the determinant is non-zero. We have now found a test for determining whether a given set of vectors is linearly independent: A set of n vectors of length n is linearly independent if the matrix with these vectors as columns has a non-zero determinant.

general eigenvectors corresponding to distinct eigenvalues are linearly independent. Thus, mathbfv1,mathbfv2 are linearly independent. Hence the lines L1,L2 spanned by […]

The way to tell if an equation is linear is by using y = mx + b. M and b can stand for any number as long it stays the same number for one equation. If the equation has a structure like this, then the equation is always linear. If an equation also has a structure like this : mx = y, then the equation is linear.
