Hello
Just took on a new hobby..being game design know a little c# and decided to try my hand at xna...the problem is I am also trying my hand at vectors and matrices also, as I know this with gaming goes hand in hand.
Kinda picking up the basics to vectors but with matrices not got a great deal of knowledge or lit on the topic
I came across these but not sure how to work it out;
A =(1 -2 3) (3 1 5) (0 1 -3) B = ( 1 -8) (-9 8 )(2 4 )
Find A x B2 (a) write out the rotation matrix that rotates an 2D object counterclockwise by 45 degrees by the coordinate origin.
b) suppose the three vertices of a triangle are A(0,0), B(10,5) and C(5,8) .Where are the vertices after the triangle is rotated counterclockwise 45 degrees by the coordinate origin?
Any help guidance would be greatful
