## What is the reciprocal identity?

In general, the reciprocal identities are identities in which the equality relation occurs by swapping or interchanging the numerator and the denominator of the number.

…

Trigonometric functions: Consider the first quadrant with the terminate point of radius r is P(x, y)..

## What are reciprocal trig ratios used for?

Reciprocal Trigonometric Functions. We can obtain graphs of the secant, cosecant, and cotangent functions as the reciprocals of the three basic functions. We can solve equations of the form secθ=k, cscθ=k, and cotθ=k by taking the reciprocal of both sides.

## How do you find the reciprocal of sin?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

## What are the 6 reciprocal identities?

Terms in this set (6)sin. 1/csc.cos. 1/sec.tan. 1/cot.cot. 1/tan.sec. 1/cos.csc. 1/sin.

## Are inverse sine and Cosecant the same?

Arcsin is the inverse trigonometric function of sine while cosecant is the reciprocal of sine. Since sine is opposite over hypotenuse, cosecant can be expressed as hypotenuse over opposite or 1/sine. … Cosecant is a separate trigonometric function and not an inverse function like arcsin.

## What are the reciprocal functions?

The reciprocal function of a function f(x) is 1/f(x). The general form of a reciprocal function is r(x) = a / (x – h) + k. … To find the asymptotes of a reciprocal function in general form r(x) = a / (x – h) + k, we use these rules: The vertical asymptote of r(x) is x = h.

## What is the reciprocal of cosine?

The cosecant is the reciprocal of the sine. The secant is the reciprocal of the cosine. The cotangent is the reciprocal of the tangent.

## How do you calculate Cotangent?

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . 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 .

## Where does cosine not exist?

Sine and cosine functions are never undefined on unit circle. They are defined at every point of a unit circle. Because according to definitions of Sine and cosine, cosine is the x-coordinate of a point moving along unit circle. Likewise, Sine is the y-coordinate of that moving point.

## What does N stand for in trigonometry?

trigonometric polynomialFrom Wikipedia, the free encyclopedia. In the mathematical subfields of numerical analysis and mathematical analysis, a trigonometric polynomial is a finite linear combination of functions sin(nx) and cos(nx) with n taking on the values of one or more natural numbers.

## Is Yr a sine?

Recall that r measures the distance from the point (x, y) ≠ (0, 0) lying on the terminal side of an angle in standard position to the origin. … Thus, cos θ = x/ r and sin θ = y/r cannot be greater than 1 or less than −1, depending on whether x and y are positive or negative (r = x when y = 0 and r = y when x = 0).

## Is the value of sin 60?

The exact value of sin(60°) sin ( 60 ° ) is √32 .

## What is reciprocal relation in trigonometry?

The trigonometric reciprocal relationships is the simplest and most basic trigonometric identities. Reciprocals of a number means 1 divided by that number. For example, the reciprocal of 4 is 14. In case of trigonometry, the reciprocal of sinΘ=1cscΘ and so on.

## What does R mean in trigonometry?

When you work with angles in all four quadrants, the trig ratios for those angles are computed in terms of the values of x, y, and r, where r is the radius of the circle that corresponds to the hypotenuse of the right triangle for your angle.

## Why is Cosecant the reciprocal of sine?

If you take a look at the unit circle, the secant is the distance from the center to the vertical tangent in a certain direction. Defined this way, the secant is the reciprocal of the cosine. Logically, its complement was called the cosecant, which is the reciprocal of the sine.
