How do find the angle between each pair of vectors below. (1 point each) a. a = 2x + 3y a = 4x + 2y

Recall that the dot product between two vectors and satisfies

where denotes the norm of a vector , and is the angle between the two vectors.

So if and , then

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
