What is linear algebra?

Q: What is linear algebra?


A: Linear algebra is a branch of mathematics that deals with the study of vector spaces and linear transformation.

Q: What is an eigenvector?


A: An eigenvector is a vector that does not change direction after undergoing a transformation, except in the case when the transformation turns it to the opposite direction.

Q: What does the term "null vector" mean?


A: A null vector is a vector of zero length or magnitude.

Q: What is an eigenvalue?


A: An eigenvalue is the value of the change in length of an eigenvector after undergoing a transformation.

Q: What is the significance of the eigenvalue in linear algebra?


A: The eigenvalue plays a crucial role in linear algebra since it helps in determining the properties of the transformation.

Q: What is the origin of the word "eigen"?


A: The word "eigen" comes from the German language, which means "own" or "typical."

Q: Can an eigenvector become a null vector after a transformation?


A: Yes, an eigenvector may become a null vector after undergoing a transformation.
