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. These concepts are central to the definition of dimension. A vector space can be of finite-dimension or infinite-dimension depending on the number of linearly independent basis vectors.

Vector Spaces (Handwritten notes)

In other words, if is a non-empty subset of a vector space then to check whether the set is linearly dependent or independent, one needs to consider the equation. Then the zero-vector cannot belong to a linearly independent set. If is a linearly independent subset of then every subset of is also linearly independent. If is a linearly dependent subset of then every set containing is also linearly dependent. We now state two important corollaries of the above theorem.

Abstract University mathematics students often find the content of linear algebra difficult because of the abstract and highly theoretical nature of the subject as well as the formal logic required to carry out proofs.

Linear independence

Once the dimension of a vector space is known, then the determination of whether or not a set of vectors is linearly independent, or if it spans the vector space, can often be much easier. In this section we will state a workhorse theorem and then apply it to the column space and row space of a matrix. We begin with a useful theorem that we will need later, and in the proof of the main theorem in this subsection. This theorem says that we can extend linearly independent sets, one vector at a time, by adding vectors from outside the span of the linearly independent set, all the while preserving the linear independence of the set. In the story Goldilocks and the Three Bears , the young girl Goldilocks visits the empty house of the three bears while out walking in the woods. One bowl of porridge is too hot, the other too cold, the third is just right. One chair is too hard, one too soft, the third is just right.

Basis (linear algebra)

In mathematics , a set B of vectors in a vector space V is called a basis if every element of V may be written in a unique way as a finite linear combination of elements of B. The coefficients of this linear combination are referred to as components or coordinates of the vector with respect to B. The elements of a basis are called basis vectors.

Any capsule summary of linear algebra would have to describe the subject as the interplay of linear transformations and vector spaces. Here we go. Conversely, these two conditions could be taken as exactly what it means to be linear.

Linear independence

Беккер внимательно слушал ее рассказ. - В самом деле спросили про секс с животными. Сьюзан пожала плечами. - Обычная проверка кандидата.

Секунду спустя оба, залившись краской, делали доклад директору Агентства национальной безопасности. - Д-директор, - заикаясь выдавил светловолосый.  - Я - агент Колиандер. Рядом со мной агент Смит.

 Нет. Думаю, англичанка. И с какими-то дикими волосами - красно-бело-синими. Беккер усмехнулся, представив это зрелище. - Может быть, американка? - предположил .

У Хейла не было мотивов для вторжения в ее компьютер. Он ведь даже не знал, что она задействовала Следопыта. А если и знал, подумала Сьюзан, то зачем ему мешать ее поискам парня по имени Северная Дакота. Вопросы, не имеющие ответов, множились в голове. А теперь все по порядку, - произнесла она вслух.

С каждым завыванием сирены слова Хейла эхом отдавались в ее мозгу: Я сожалею о Дэвиде Беккере. Сьюзан казалось, что она сходит с ума. Она уже готова была выскочить из комнаты, когда Стратмор наконец повернул рубильник и вырубил электропитание. В одно мгновение в шифровалке установилась полная тишина.

 Лаборатория вне закона? - спросила Сьюзан.  - Это что за фрукт. Соши пожала плечами.
