Hi Guys and Girls,

I have the following problem and have no idea about where to start.

Give an example of a 2 by 2 rotation matrix that rotates the point

( 7 , 7 )

into the square with corners

( -1 , -10 )

( 1 , -10 )

( 1 , -8 )

( -1 , -8 )

I have a feeling that I would need to use the rotation matrix

But am confused as to what the points would be.

Cos(x) -Sin(x)

Sin(x) Cos(x)

n

Thanks
