We will begin our journey through linear algebra by defining and conceptualizing what a vector is (rather than starting with matrices and matrix operations like in a more basic algebra course) and defining some basic operations (like addition, subtraction and scalar multiplication).
Watch Sal change the magnitude of a vector by multiplying it by a scalar.
Visually understanding basic vector operations
Practice basic scalar multiplication.
Watch Sal explain unit vectors including a variety of notation.
Find a unit vector in the direction of a given vector.
Add and subtract vectors given in component form.
Add two vectors in magnitude and direction form to get a new vector in component form.
