The lunar corrections involving sines are small compared with those 
involving cosines. 
To evaluate these corrections we must compute 7 from 9 reduced to 
time at 14°°49 per hour. 
In the right ascensional terms, da/d and o are to be expressed in 
degrees perhour. da/dt is the hourly change of )’s R.A. at time of 
)’s transit, and da,/dé is the hourly change of ©’s R.A. at time of )’s 
transit.
