“Lastly, if you put⟳ BC the lesser of the sides, including the right angle for Radius, the greater side, AC, including the right angle is the tangent of ABC, the greater acute angle opposite; and the subtendent A B, is the secant of the same acute angle.”

“The very Subtendent line is found of an odde part; but the very subtendent of an even part is not found at one operation, but onely the Square of the Subtendent; and the greater the number⟳ of parts be, so much harder it willbe to finde out the subtendent.”

“The first figure⟳, Vale, hath but one mood, and therefore of as great extent as it selfe, which is Upalem; whose nature is to let⟳ us know⟳, whan a plane right angled triangle is given us to resolve⟳, whose subtendent and one of the obliques is proposed, and one of the ambients required, that we must have⟳ recourse unto its resolver, which being Rad_U_Sapy→Yr sheweth, that if we joyne the artificiall sine of the angle opposite to the die⟳ demanded with the Logarithm of the subtendent, the summe searched in the canon of absolute numbers will afford⟳ us the Logarithm of the side required.”

“For example, even if there were no possible quantity, mathematicians could say⟳ that if it was possible to make⟳ a right angled triangle, it was something assured that the hypotenuse or the subtendent of the right angle would make⟳ a square equal to the squares of the other two sides”
