Then, the sequence {[x.sub.n]} generated by the modified
secant method (4), starting from any two initial points [x.sub.0], [x.sub.-1] [membe rof] B([x.sub.*], R), converges to the solution [x.sub.*].
In this research work
secant method was employed to trial linear and quadratic congruences along with higher degree congruences.
Another advantage is that the
secant method can be used to approximate complex roots, as well, if the initial values [x.sub.0] and [x.sub.1] are taken to be complex numbers satisfying the conditions above.
where, depending to the
secant equations (1.4) and (1.5), [v.sub.k] = [y.sub.k] in [1, 2, 3, 4, 5] and [v.sub.k] = [z.sub.k] in [9], and also, [[theta].sub.k+1] is a scaling parameter determined based on a two-point approximation of the corresponding
secant equation [14, 27], i.e.,
(Note that the tangent formulas can be obtained from the
secant ones by calculating the limit as [[phi].sub.1] and [[phi].sub.2] approach [[phi].sub.0].) Although conformal conic mappings have no exact geometric meaning, the terms
secant and tangent are widely used both in cartography and in atmosphere-ocean modeling [3,5,9,10, 12, 21].
We need two starting values for
Secant Method to proceed.
During the first baseline condition, participants were assessed regarding their ability to construct formulas for graphs representing transformed sine, cosine,
secant, and cosecant functions displayed as scattered data points on the coordinate axes.
RECON's geotechnical division specializes in the construction of underground barriers such as slurry cutoff walls, slurry diaphragm walls, soil mixing and deep soil mixing,
secant walls and jet grouting while the civil services division specializes in site preparation, excavations, earthwork construction, soil and sludge stabilization, site development and concrete work.
The
secant ogive tapers faster than a tangent ogive.
