What transformation matrix would result in a 300 degrees counterclockwise rotation about the origin? i cant type all of the options, but they all look like fractions inside brackets, some with square root signs.

For rotation by an angle, θ, in the counter-clockwise direction about the origin, the transformation matrix is given by 
     

The given angle is θ=300°. 

The values we need are
     
     

Substituting these into the given transformation matrix, we have
