give identical values of Euler angles except around discontinuous switching. The
spikes in the roll angle 4 for a = 45 deg (Fig. 4.13) are apparently caused by the
fact that Euler angle rates assume large values as 0 approaches 90 deg.
Example 4.6
  At a certain time during a continuous motion of an airplane, the following
direction cosine matrix is recorded.Itis suspected that the elements marked xx are
in error and hence are discarded. Determine the missing elements.
    0.8999 -0.4323  0.0578 -1
C- xx  0.8665 -0.2496
      1        :    0.9666 j
     xx    xx
   Solution.   We observe that the missing elements are C21, C31, and C32. We
have rune elements of the direction cosine matrix and six redundancy relations.
