# What is the definition of secant of a circle?

Space and AstronomyDefinition of secant 1 : **a straight line cutting a curve at two or more points**. 2 : a straight line drawn from the center of a circle through one end of a circular arc to a tangent drawn from the other end of the arc.

## Where is a secant of a circle?

What is the Secant of a Circle? **A line that intersects the circle exactly at two distinct points** is the secant of the circle. A secant line includes the chord and is always extended outside the circle. In other words, if the chord is extended on both sides it becomes the secant.

## What is meant by tangent and secant of a circle?

**A line that intersects a circle in exactly one point is called a tangent and the point where the intersection occurs is called the point of tangency**. The tangent is always perpendicular to the radius drawn to the point of tangency. A secant is a line that intersects a circle in exactly two points.

## What is secant of a circle class 9?

Secant: The secant of a circle is **a straight line that intersects the circle at two distinct points**. So, a line that touches the circle at two points is called a chord and a line that intersects the circle at two distinct points is called a Secant.

## What is the secant in math?

A secant line, also simply called a secant, is **a line passing through two points of a curve**. As the two points are brought together (or, more precisely, as one is brought towards the other), the secant line tends to a tangent line.

## How do you name a secant in a circle?

Video quote: *It at two points and those points are not both endpoints of the line segment because if both of those points were endpoints of the line segment. We would just call that segment a chord of the circle.*

## What is secant of a circle class 10?

A secant is **a line that intersects the circle at 2 distinct parts**.

## What is the secant formula?

The secant formula helps in finding out the hypotenuse, the length, and the adjacent side of a right-angled triangle. The formula is **sec θ = H/B**.

## Is chord a secant?

Chords are segments connecting two points on a circle, so **chords become secants when extended**.

## How do you find the secant and tangent of a circle?

Video quote: *So it turns out that the tangent segment is the geometric mean of the external part of the secant segment times the entire length of the secant segment.*

## How do you get secant?

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 .

## How do you use secant?

Video quote: *Data is adjacent over hypotenuse so the secant of theta is hypotenuse over adjacent now knowing that PI over three is the same thing as 60 degrees.*

## Is secant opposite of cosine?

**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.

## How do you do secant on a calculator?

Video quote: *And now if I wanted the secant of PI twelfths okay in the calculator. I have to use the reciprocal function so I'm going to do 1 over the cosine of PI. 12 now this is in radians. So.*

## Where is SEC on ti84?

Video quote: *But there are no cosecant cotangent or secant functions. So we can sort of get around this by using fractions.*

## How can I reverse my sins?

The idea is the same in trigonometry. Inverse trig functions do the opposite of the “regular” trig functions. For example: Inverse sine ( sin − 1 ) (\sin^{ -1}) (sin−1)left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the sine.

## How do you find sin?

**To find sin, cos, and tan we use the following formulas:**

- sin θ = Opposite/Hypotenuse.
- cos θ = Adjacent/Hypotenuse.
- tan θ = Opposite/Adjacent.

## What is cos over sin?

For a right triangle with an angle θ : Sine Function: sin(θ) = Opposite / Hypotenuse. Cosine Function: cos(θ) = **Adjacent / Hypotenuse**.

## Is YX a tan?

The unit circle definition is **tan(theta)=y/x** or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. We talked about the sine and cosine functions.

## What is sin θ?

Looking out from a vertex with angle θ, sin(θ) is **the ratio of the opposite side to the hypotenuse** , while cos(θ) is the ratio of the adjacent side to the hypotenuse . No matter the size of the triangle, the values of sin(θ) and cos(θ) are the same for a given θ, as illustrated below.

## Is PB a tan?

Hypotenuse (the side opposite to the right angle).

No | Points studied |
---|---|

2 | cosine = Base/hypotenuse(BH) |

3 | tangent = Perpendicular/base(PB) |

4 | cosecant is reciprocal of sin |

5 | secant is reciprocal of cos |

## How do you write cosecant?

Cosecant is one of the main six trigonometric functions and is abbreviated as **csc x or cosec x**, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.

## What is tan math?

Tangent, which is commonly abbreviated to three letters as T-A-N, is **the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle**. The adjacent side is the one touching the angle that is NOT the hypotenuse, which is the side opposite the right angle.

## What is tangent physics?

In physics or mathematics tangent has same concept. It is defined as: A tangent line is **a straight line that touches a function at only one point**. The tangent line represents the instantaneous rate of change of the function at that one point.

## What is CSC math?

In a right angled triangle, the cosecant of an angle is: **The length of the hypotenuse divided by the length of the side opposite the angle**. The abbreviation is csc. csc θ = hypotenuse / opposite. It is not commonly used, and is equal to 1/sine.
