Vector Components and Displacements

The video tutorial explains how to write vectors in component form using angle brackets. It introduces the concept by using ordered pairs of initial and terminal points. The tutorial provides a formula for determining the component form of a vector and demonstrates this with examples of vectors U and V. Each vector's components are calculated and verified graphically. The video concludes with a summary of the key points covered.

What is the formula for the x component of a vector given its initial and terminal points?

• x2 + x1

• x2 - x1

• x1 - x2

• x1 + x2
