Quick Answer: What Is Secant In Math?

What is SEC equal to?

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x, and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x.

What is Secant formula?

Secant is derived from the cosine ratio. 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. In formulas, it is abbreviated as ‘ sec ‘. It has a period of 2 pi, similar to sine and cosine.

What is Secant the opposite of?

The three most common trigonometric ratios are sine, cosine, and tangent. Cosecant is the reciprocal of sine. Secant is the reciprocal of cosine. Cotangent is the reciprocal of tangent.

What is difference between chord and secant?

A chord is the line segment that joins two distinct points of the circle. In geometry, a secant is a line that cuts any curve in at least two different points.

What is Secant function?

The secant function (usually abbreviated as sec ) is the reciprocal function of the cosine function. Remember that point P is a point on the circumference of the circle whose x and y coordinates represent the value of cos (θ ) and sin (θ ) respectively (the line segments representing the sine and cosine are also shown).

What is SEC on a calculator?

Description. Secant function. SEC (x) returns the secant of x. To convert degrees to radians you use the RADIANS function.

What is Secant graph?

As with tangent and cotangent, the graph of secant has asymptotes. This is because secant is defined as. The cosine graph crosses the x-axis on the interval. at two places, so the secant graph has two asymptotes, which divide the period interval into three smaller sections.

Is SEC the opposite of Cos?

The secant ( sec ⁡ ) ( sec ) ( sec ) The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

Is sin 1 the same as CSC?

cosecant is the reciprical of the sin function or 1 / sin (x) so that csc (x)* sin (x) = 1 when it is defined. The two can be confused since arcsin(x) is often denoted as sin ^- 1 (x) and x^- 1 is 1 /x.

How do you prove identity?

For instance, sin(x) = 1/csc(x) is an identity. To ” prove ” an identity, you have to use logical steps to show that one side of the equation can be transformed into the other side of the equation. You do not plug values into the identity to ” prove ” anything.

Does a secant line contains a chord?

A secant line is a line that intersects a circle at two points. Every secant line, therefore, contains a chord of the circle it intersects.

Is a chord a ray?

Chords: A chord of a circle is a segment that you draw from one point on the circle to another point on the circle. A chord always stays inside the circle. Tangent: A tangent to a circle is a line, ray, or segment that touches the outside of the circle in exactly one point. It never crosses into the circle.
