magnitude of 0, no given direction

How do you find the direction of a vector given its components?

• Use the arctan function to find the angle between the vector and the x-axis.

• Use the tangent function to find the angle between the vector and the y-axis.

• Use the sine function to find the angle between the vector and the y-axis.

• Use the cosine function to find the angle between the vector and the x-axis.
