ese the curve may bedrawn. (See also Problem 14.) 55. The Catenary is the curveassumed by a perfectly flexible cordwhen its ends are fastened at twopoints, the weight of a unit lengthbeing constant. The equation of the catenary is »-l(^.~5). in which e is the base of the Napierian system of… … ; (1.396+0.717) =3.17. (e3 + e 3)= I (1.948+0.513) =3.69. Then put x = l; .. VPut z = 2; .. y- Put x = 3 4 5 etc etc., and find the corresponding values of y. Foreach value of y we obtain two symmetrical points, as for example p and p.In this way, by making a successively equal to 2, 3, 4, 5, 6, 7,…
