A vector has both magnitude and direction. We use vectors to, for example, describe the velocity of moving objects. In this video, you'll learn how to write and draw vectors.

Unit vector notation (part 2) Optimal angle for a projectile part 1: Components of initial velocity. Optimal angle for a projectile part 2: Hangtime. Optimal angle for a projectile part 3: Horizontal distance as a function of angle (and speed)
For a given point, if you draw an arrow from the origin up to that point, this arrow would be represented with that same triplet of numbers, but you typically do it in a column, I call this a column vector.
Review different forms of vectors and learn about their magnitude and direction.
Determining the equation for a plane in R3 using a point on the plane and a normal vector
Learn how the gradient can be thought of as pointing in the "direction of steepest ascent". This is a rather important interpretation for the gradient.

We see the direction of vector a is 30 degrees counter-clockwise of due East. Now in this video, we're gonna talk about other ways or another way to specify or to define a vector. And that's by using components. And the way that we're gonna do it is, we're gonna think about the tail of this vector and the head of this vector.
