rotating-points-using-rotation-matrices

In this video I justify the formula used involving matrices to help find the new coordinates of a point after a counter clockwise rotation. There is one quick example as well at the end! The formula is pretty easy to use so long as your remember matrix multiplication so I spent more time on the justification part since it is more interested!
