Front

Define a vector.

Back

A vector is a mathematical object that has both a magnitude and a direction.

Front

What is the formula to calculate the magnitude of a vector ?

Back

Magnitude = √(x² + y²)

Front

What does it mean for two vectors to be equivalent?

Back

Two vectors are equivalent if they have the same magnitude and direction.

Front

How do you find the direction of a vector in standard position?

Back

The direction is found using the angle θ = arctan(y/x) for vector .

Front

What is the standard form of a vector?

Back

A vector in standard form is represented as where x and y are its components.
