Python

-Write a function named dot that calculates the dot (inner) product of two vectors. It should take two arguments assumed to be three-element tuples, each representing the (x, y, z)components of a vector. It should return a number corresponding to the dot product of those two vectors.

-Write a function named angle_between that takes two arguments, assumed to be vectors represented as 3-tuples, and returns the angle between them (in radians).

Hint: The easy way to do this is to calculate the dot product of the two vectors using your dotfunction, and then take advantage of the alternate dot product expression

A B = A B cos(CAB
