Calc 3 - vectors (type 2)

MV calc notes

same length means...?

same magnitude

Multiplying a vector by a value greater than 1 does what to the vector?

makes it longer

Multiplying a vector by a value between 0 and 1 (proper fraction) does what to the vector?

makes it shorter

Multiplying a vector by a negative value does what to the vector?

reverses direction

vectors with the same or opposite direction are….

parallel vectors

A vector with a magnitude (length) of 1….

unit vectors

two vectors that have the same magnitude and the same direction

equal vectors

two vectors whose dot product equals zero….

orthogonal vectors

if angle between the vectors is 90 degrees, the dot product is

zero

acronym for cross product

Output for dot product = (vector or scalar)?

scalar

Output for cross product = (vector or scalar)?

3D vector

Cross product of a x a = ?

zero
