# Writing a linear combination of unit vectors in cartesian

It contains links to the contemporary mathematical and scientific literature. I describe some of the chance events in and that led to my three-year immersion in this study, in which I was guided by both mathematics and physical experimentation. I benefited greatly from discussions with several eminent mathematicians, some of whom appear in photos below, but especially useful in my study of the geometry of periodic structures were the two books 'Third Dimension in Chemistry', by A. Wells and 'Regular Polytopes', by H. ## Mathguru â Homework Help and Indiaâs First Online Mathematics Learning Program

This lesson covers how to find linear combinations of vectors. A linear combination uses two basic vector operations: A linear combination is any finite combination of both scalar multiplication and vector addition. For example a linear combination of three terms looks like: Where, and are scalars and, and are vectors.

Each operation has both an algebraic and geometric interpretation.

Learning Goals Compute linear combinations by using scalar multiplication and vector addition. Scalar multiplication changes the magnitude of a vector by stretching or shrinking it. If the scalar is negative, it will also reverse the direction.

Vector addition is done geometrically by putting the tail of the second vector at the tip of the first. Additionally the order does not matter because of the parallelogram law. Find a unit vector in the direction of a given vector. Express 3-D vectors using the Cartesian basis vectors, and. Work with vectors expressed using Cartesian basis vectors. Scalar Multiplication Scalar multiplication is an operation which takes a scalar,and a vector,and multiplies them together to create a new vector. Algebraic Definition If a vector is written in component form, the scalar product is the scalar multiplied by each component of the vector. If is a scalar and If is a 2-D vector, then If is a 3-D vector, then Geometric Definition Scalar multiplication stretches and shrinks the length of the vector by the factor. If is negative, the direction of the vector is reversed.

Algebraically the property that scalar multiplication scales the magnitude of a vector can be expressed as Finding Unit Vectors A unit vector in the direction of can be found scaling the magnitude of to 1 using scalar multiplication: Vector Addition Vector addition is an operation which takes two vectors, andand adds them together to create a new vector.

Algebraic Definition If the vectors are written in component form, then their sum is found by adding the corresponding components together. If and are 2-D vectors, then If and are 2-D vectors, then Geometric Definition The vector is added to by placing the tail of at the tip of in a tip to tail diagram.

The sum is the new vector that points from the tail of to the tip of as shown: In this definition the order you add the two vectors, oraffects the order you draw the two vectors. But due to the parallelogram law, both orders give the same resulting vector as shown: Linear Combinations A linear combination is any finite combination of scalar multiplication and vector addition.

Each of the above basis vectors is a unit vector that points in one of the three Cartesian coordinate directions. Every vector in 3-D can be written as a linear combination of these basis vectors.

If is a vector then: This is verified by computing the linear combination: Geometrically every vector can be created by moving only in the coordinate directions:Vectors in the Plane Many quantities in geometry and physics, such as area, time, Writing a Linear Combination of Unit Vectors Let u be the vector with initial point (2, -5) and terminal point (-1, 3).Write u as a linear combination of the standard unit vectors i and j.
