Should the result vector not be 0, -1, 0?

If you believe its 0 , 1 , 0 please explain how you get it because i get 0 , -1 , 0.

Thanks.

Example: Rotation ( cos 90 0 sin 90 - sin 90 cos 90 0 0 1 0 Consider the vector (1,0,0) Now 90 CCW rotate around the x-axis, then 90 CCW around the Z-axis Note the order: V = Rxy (90)Ryz(90) v Order of rotation matters cos 90 sin 90 0 - sin 90 cos 90 pore Ray Soy Py=(8017 The result is: V = The result is: V = ()
