This is a vector: A vector has magnitude (size) and direction: The length of the line shows its magnitude and the arrowhead points in the direction.

Enter values into Magnitude and Angle ... or X and Y. It will do conversions and sum up the vectors. Learn about Vectors and Dot Products.

A vector has magnitude (how long it is) and direction ... Here are two vectors

They have many uses ... A simple example is that an eigenvector does not change direction in a transformation ... How do we find that vector?

A vector has magnitude (how long it is) and direction: Two vectors can be multiplied using the Cross Product (also see Dot Product).

One of the last examples on Systems of Linear Equations was this one: x + y + z = 6. 2y + 5z = 4. 2x + 5y z = 27.

A vector has magnitude (how long it is) and direction: A Unit Vector has a magnitude of 1: A vector can be scaled off the unit vector.

Illustrated definition of Component (vector): When we break a vector into two or more parts, each of those new vectors is a component of the original...

Speed is how fast something moves. Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed.

Undetermined Coefficients which only works when f (x) is a polynomial, exponential, sine, cosine or a linear combination of those. Variation of Parameters (that we will learn here) which works …
