The periphery of every circle is supposed to be divided into 360 equal parts ;
called degrees ; and each degree into 60 equal parts , called minutes ; and each
minute into 60. equal parts , called seconds , or second minutes , & c . Bz 3.

The fines of every degree and minute , up to 60 ° , being thus found ; those of
above 60 ° will be had by addition only ( from Theor . 2. p . 15. ) then , the fines
being all known , the tangents and fecants will likewise become known , by Prop .
