Secant Triangle Math
It has a period of 2 pi similar to sine and cosine.
Secant triangle math. It is written as sec and the formula for secant is. Secant is a name and it is introduced in trigonometry to represent the ratio of lengths of hypotenuse to adjacent side at a particular angle in a right angled triangle. In a right triangle the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. These are basically six in number.
The formula for secant theta. The secant of an angle in a right triangle is the hypotenuse divided by the adjacent side. Secant sec is a trigonometric ratio. A secant is a line that intersects a circle at two points.
In a right angled triangle the secant of any angle will be the ratio of the length of the hypotenuse and the length of the adjacent side. Secant sec trigonometry function see also secant of a circle. A term that represents a ratio of lengths of hypotenuse to adjacent side at an angle of a right triangle is called the secant. In a right triangle with an angle theta sec theta frac mbox hypotenuse mbox adjacent text adjacent is the side of the triangle that is part of angle theta and text hypotenuse is the side opposite the right angle.
In a formula it is abbreviated to just sec. The length of the hypotenuse when divided by the length of the adjacent side becomes the secant of an angle in a right triangle. C 2011 copyright math open reference. Secant is derived from the cosine ratio.
It is usually written in ratio form and alternatively as secant with angle. In formulas it is abbreviated as sec. What are secant cosecant cotangent. See secant of an angle trigonometry.
