secant, in mathematics. 1 In geometry, a secant is a straight line cutting a curve or surface. If it intersects the curve in two different points, as in the secant of a circle circle, closed plane curve consisting of all points at a given distance from some fixed point, called the center. Secant definition is - a straight line cutting a curve at two or more points.
Definition of Secant Function The secant of an angle is one over its cosine. In a right angled triangle, the secant of an angle is equal to the length of the Secant Function - Math Definitions - Letter S. secant, in mathematics. 1 In geometry, a secant is a straight line cutting a curve or surface. If it intersects the curve in two different points, as in the secant of a circle , the segment of the secant between the points is called a chord. Definition of the Inverse Secant Function From trigonometry, we know that the secant function is defined by sec x 1 cos x. Since cos x 0 at x /2, 3 /2, 5 /2. etc. all odd multiples of /2, the secant. secant sec. The trig function secant, written sec θ. sec θ equals. For acute angles, sec θ can be found by the SOHCAHTOA definition as shown below on the left. The circle definition, a generalization of SOHCAHTOA, is shown below on the right.

Meaning, pronunciation, translations and examples. 24/12/2019 · - [Voiceover] A secant line intersects the curve y equals the natural log of x at two points, with x-coordinates two and two plus h. What is the slope of the secant line? Well, they're giving us two points on this line. It might not be immediately obvious, but they're giving us the points when x is.
In calculus, the secant line is a line that locally intersects a curve twice. It is used to approximate the slope within a particular interval. In the image, the line that intersects twice is called the secant line, the line tangent to a point is the tangent line. This is where the geometric definition. secant - WordReference English dictionary, questions, discussion and forums. All Free.
