Explanation:
"Assuming a rotation about the origin"Assuming a rotation about the origin
"under a clockwise rotation about the origin of "(3pi)/2under a clockwise rotation about the origin of 3π2
• " a point "(x,y)to(-y,x)∙ a point (x,y)→(−y,x)
rArr(2,2)to(-2,2)⇒(2,2)→(−2,2)
rArr(6,-3)to(3,6)⇒(6,−3)→(3,6)
