Lesson 8: Component form of vectors

# Vector components from magnitude & direction (advanced)

Find a vector's components from its magnitude and direction. Direction angle is not given directly.

## Introduction

Each of the two problems below asks you to convert a vector from magnitude and direction form into component form.
But watch out! The direction angles aren't given for these vectors. You'll need to be careful what you plug into the sine and cosine functions.

## Problem 1

The vector v, with, vector, on top is shown below.
Find the component form of v, with, vector, on top.
v, with, vector, on top, approximately equals, left parenthesis, space
space, comma
right parenthesis, space

## Problem 2

The vector u, with, vector, on top is shown below.
What is the component form of u, with, vector, on top?
