Subject: Using a sine bar and v-block to measure taper.

I have been trying to measure a #3 Morse
taper using the method described on page 652 of
the 24th edition of Machinerys Handbook.
 
I have had little success so far.  Does the formula
for Sine C ask for the sine of A divided by 2 or the
sine of 1/2 angle A?  Any help most gratefully welcome.
