But , first of all , it will be proper to observe , that the fine of any arch Ab greater
than 90 ° . is equal to the line of another arch AB as much below 90 ' ; and that ,
its co - line Cf ; tangent Ag , and secant Cg , are also respectively equal to the co

Thus , if an = 2 , and a " = 3 , then will m and n be logarithms of the numbers 2
and 3 respectively . Hence it is evident , that what bas been above per cified , in
relation to the properties of the indices of powers , is equally true in the
logarithms of ...

tangent of half the bypothenuse , is to its tangent ; so is the co - line of the
difference of the angles at the hypothenuse , to the fine of the excess of their sum
