Hey KingJohnno.
Hint: Try expanding out your linear system to get solutions in terms of sin(x) and cos(x) and then find x with respect to the right quadrant using arc-cos and arc-sin.
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
Cos(x) -Sin(x)
Sin(x) Cos(x)
But am confused as to what the points would be.
Thanks
KJx
