QUESTION 8
An object initially had its axes and origin coincident with the world axes and origin. It was then rotated 30 degrees about the x-axis and then 45
degress about the y-axis.
Call M the matrix for the 30 degrees about x-axis rotation, and N the matrix for the 45 degrees about y-axis.
Then the final transformation can be modeled by a matrix R. What is R22 (the element of R in row 2 and column 2)? (Round to 3 decimal places, if
needed)
