the simple way to culculate this value is to ist consider the basic trignometric ratio near to 20. Than we come that 30 is near to it and cos30 is equal to 0.866 now for 1 dgree rise or fall the costheta decrese by the factor 0.0009 since cos20 is 10 dgree far frm thrty so multiply 0.0009 by 10 and subtract from 0.866.
