Trrnlisc on Plane and Spkrricnl Trigonometry, By Robert Woodhouse, A.M. F.R.S. Follow of' Caius Collie, Cambridge. London, 1809. I KiGONOMEThY is Otic cf the branches of the mathematics, which has received the greatest number of successive improvements, and has adv.inc-fd the frrrhest beyond the boundaries wirhin which it was origin illy confined. It dates its origin from the time of Hipnsrchns; 'and may basr, that its foundations were laid by the sjme person who first undertook to number the stjrs, and, in the lanjf u: -.y;e of Plinv, to leave the heavers for an tnhf ritnnce to posterity. We do rot know, from the writings of this astronomer, or those of his coieippcrari, by what circumstances he wns Jed;o aply number to measure the sides and the angles of tri.ir.jjles; but, in the history of a science, of which the objects an all i.ccessarily connected with one another, tbe want of direct testimony may often be safely supplied by theoretical conjecture. This, we believe, is true, in the present instance. Geometei were, Do doubt; t first, satisfied, in the solution of problems, to cfrrermine the things sought from the things g;ven by geometrical construction; tint is, by mere graphical operations, or br drawing their figures, as we do, with conipnsses and a scale of equal p rts. This would tu? suiFiciently exact for common use, and for all the orniiviry purposes of mensuration, whether of lines cr surfaces. Cjses, however, would sometimes- occur, where the errors iof tuch a method uvre too great to be overlooked, and where the results were palpably inconsistent with one another. When, for example, there were given in a triangle, the rne and the adjacent angles, to determtie the sides; and when, at the same time, it happened that the sum of the given angles...
