Question

What is the name given to \[\vec{OP}=x\hat{i}+y\hat{j}+z\hat{k}\]?

Options

• scalar multiplication

• component form of a vector

• collinearity of vectors

• magnitude of a vector

Answer 1

A vector written using its components along \[\hat{i},\hat{j},\hat{k}\] is called the component form of a vector. The coefficients give the components in the three coordinate directions.
