As this error is positive p must be diminished: therefore 
suppose p = 0*3 ; then

By comparing the two errors it will appear that p is between 
0*32 and 0*33: suppose p = 0*33, and because the errors are 
now small, let all the terms of the final equation be taken into 
account ; then 
z=. 0*864306
