# Vectors - Lessons & Resources

Need help on vectors?

We have a collection of introductory lessons on vectors, equality of vectors, basic
operations on vectors, vector geometry, position vectors, etc., as well as more advanced lessons
on vectors and parametric equations, components of vectors, dot product of
vectors, 3-dimensional vectors and more.

We also have a a vector calculator that can help you to find the
length of vectors, add vectors, subtract vectors, multiply
vectors, calculate cross product and dot product of vectors. Use
it to check your answers!

### Vector Introduction

A vector quantity has both magnitude and direction.

Problems involving velocities, displacements, forces and navigation are often made easier when vectors are used.

The topics covered in these introductory lessons on vectors are:
