Finding Image Points for 90° Counterclockwise Rotations
What are the coordinates of F'?
Use the work shown to find the image of point F(-1,6)
after a 90° counterclockwise rotation,
(x, y) - (-y, x)
Switch the x-and y-coordinates: (6,-1)
*
(6,-1)
(-6,1)
(-6,-1)
(6,1)
Multiply the new x-coordinate by-1: (6(-1), -1)
Simplify

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

use formula for the circle a=3.14
