0 in a triangle that has one angle of 90°, the ratio of the hypotenuse (= the length of the side opposite the 90° angle) to the length of the side next to an angle less than 90° --
1 in a triangle that has one angle of 90°, the ratio (=comparison) of the hypotenuse (= length of the side opposite the 90° angle) to the length of the side next to an angle less than 90° --
The secant lines of isograds with the surface form lines on a geologic map.
The algorithm tries to use the potentially fast-converging secant method or inverse quadratic interpolation if possible, but it falls back to the more robust bisection method if necessary.
The method is a generalization of the secant method.
A secant line, or just "secant", is the line extension of a chord.
In fact, the union of the tangent and secant lines of any non-planar smooth algebraic curve is three-dimensional.
He inserted an additional test which must be satisfied before the result of the secant method is accepted as the next iterate.
Here we have assumed already known the integral of the secant function.
A chord is an interval of a secant line, the portion of the line that lies within the curve.
