Calculates the new coordinates when the coordinate axes are rotated around the origin.
Original coordinates (x
,
y)
Rotation angle θ
(θ: Clockwise rotation indicates a negative input)
New Coordinates (X ,Y )
\(\normalsize Rotation\ of\ axes\hspace{20px}\theta: (x,y)\rightarrow (X,Y)\\ \hspace{20px}X=x \cos(\theta)+y \sin(\theta)\\ \hspace{20px}Y=-x \sin(\theta)+y \cos(\theta)\\\)
