Which matrix represents the rotation of the vector 1,4 by 2pi/3 radians

Option B is correct.

Rotation matrix =

Step-by-step explanation:

Given a vector : , rotation by radian.

A rotation matrix is a matrix that is used to perform a rotation in Euclidean space.

The standard rotation matrix is given by;

R =

Then, the matrix of rotation by radian  is:

=

Then; substitute

or

or

Simplify:

Therefore, the rotation matrix of a given vector is,

the bottom of the spinner is not flat.
