For the following exercises, determine which (if any) pairs of the following vectors are orthogonal. Verify the identity $\mathbf{u} \cdot(\mathbf{v}+\mathbf{w})=\mathbf{u} \cdot \mathbf{v}+\mathbf{u} \cdot \mathbf{w}$ for vectors $\quad \mathbf{u}=\langle 1,0,4\rangle, \quad \mathbf{v}=\langle- 2,3,5\rangle, \quad$ and $\mathbf{w}=\langle 4,-2,6\rangle$

Key Concepts

Vector Addition

Vector addition is the process of combining two or more vectors to produce another vector. This is done by adding the corresponding components of the vectors, and it is a fundamental operation in vector algebra, heavily used in physics, engineering, and computer science to solve problems involving direction and magnitude.

Distributive Property of the Dot Product

The distributive property of the dot product states that the dot product of a vector with the sum of two other vectors is equal to the sum of the dot products of the vector with each of the other vectors individually. This property underpins many algebraic manipulations in vector calculus and linear algebra and is essential for verifying identities and simplifying expressions involving vectors.

Orthogonal Vectors

Orthogonal vectors are pairs of vectors that meet at a right angle, meaning their dot product is zero. This property is used to determine whether two vectors are perpendicular to each other, playing a crucial role in analyses involving projections, decompositions, and many areas of physics and engineering.

Dot Product

The dot product, also known as the scalar product, is a mathematical operation that takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number. This operation is calculated as the sum of the products of the corresponding entries of the two sequences, and it is a measure of the extent to which two vectors point in the same direction.
