Labels:book | reckoner | sky | tree | windowpane OCR: 1-72 Mops Tutorial As an overview, we can say that the math calculations first convert the degree value to be in the range 359 Allowance made for degree values entered as negative numbers. or degrees of magnitude 360 or greater Once the degree is thus normalized IS converted to the equivalent degree in the range 0 89 and the quadrant is saved 10J doing mirror image calculations and determining the sign. For degrees on an axis 90 180 or 270) the sine gotten from the ivar Axis Vals, since this is the simplest way to handle these special cases. Otherwise lookup per formed on the Trig Table array To best understand the operation of the decision processes in this section, we will follow what happens to the values on the stack when we try degree values less than 90 degrees, exactly 180 degrees, ...
