    C = 60      Doe, a deer, a female deer
D = 62      Ray, a drop of golden sun
E = 64      Me, a name I call myself
F = 65      Far, a long long way to run

A = 69      La, a note to follow sew
B = 71      Tea, I drink with jam and bread
C = 72      That will bring us back to do...oh oh oh

  1. Practice with Maya and the RotationY attribute of a polygonal cube that was animated to rotate a full 360 degrees from Frame #1 to Frame #50. Ease in and Ease out and a tweening graph representing the frame by frame changes beTWEEN frame #1 KeyFrame and frame #50 KeyFrame.

  2. Using the SHODOR Data Flyer tool to investigate the EASE IN graph for the animation of the polygonal cube's rotationY property. X, Y, Z equals R, G, B as in Red, Green, Blue graphics. 
     y = mx + b    m is the slope      
               b is the intercept
               x is the point in time, the frame #, which is 1, 2, 3, ..., 49, 50.
               y is the degrees of rotation on the Y axis of the polygon.
               y is a value between 0 and 360

 Here are the (x, y) pairs for frames 1, 2, 3, 4, 5, 6 and 7

                     1  0
                     2  0.444
                     3  1.75
                     4  3.883
                     5  6.805
                     6  10.48
                     7  14.871
  3. After the TANGENTS are converted to LINEAR we have (1, 0), (2, 7.347), (3, 14.694), (4, 22.041) 
    Frame	rotateY
  1	 0
  2	 7.347
  3	14.694    EASE IN is gone and the graph is a straight line.
  4	22.041
  5	29.388    The slope of the line is the same everywhere.
  6	36.735
  7	44.082    Try using Data Flyer on these 7 different (x, y) pairs.
                  What will be the best sum of squares of deviations be?  Why?
