# What Is The Reciprocal Of Sin A?

## What does N stand for in trigonometry?

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..

## What are the six trigonometric functions?

The trigonometric functions include the following 6 functions: sine, cosine, tangent, cotangent, secant, and cosecant.

## What are the 2 quotient identities?

In trigonometry, quotient identities refer to trig identities that are divided by each other. There are two quotient identities that are crucial for solving problems dealing with trigs, those being for tangent and cotangent. Cotangent, if you’re unfamiliar with it, is the inverse or reciprocal identity of tangent.

## What is CSC of an angle?

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.

## What is sin a and sin B?

The sum formula works whether both angles are the same or different: sin(A + B) or sin(A + A). However, sin(A + A) is really sin 2A. So, sin 2A is sin A cos A + cos A sin A. They are both the same product, in opposite order, so this statement can be simplified to sin 2A = 2 sin A cos A.

## Is Tan Cos sin?

Each of these functions are derived in some way from sine and cosine. The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

## Is Yr a sine?

First, the the secant, cosecant, and cotangent functions are the reciprocals of the cosine, sine, and tangent functions, respectively. Second, there is no value for which the cosine and sine functions are undefined. This is because r is the distant from the origin to the point (x,y) ≠ (0,0) on the terminal ray.

## What does Sine mean?

In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).

## How do you make a reciprocal?

The definition of “reciprocal” is simple. To find the reciprocal of any number, just calculate “1 ÷ (that number).” For a fraction, the reciprocal is just a different fraction, with the numbers “flipped” upside down (inverted). For instance, the reciprocal of 3/4 is 4/3.

## What is the ratio of cot θ?

Allied to these are the three reciprocal ratios, cosecant, secant and cotangent: cosecθ=hypotenuseopposite,secθ=hypotenuseadjacent,cotθ=adjacentopposite. cosecθ=1sinθ,secθ=1cosθ,cotθ=1tanθ.

## What is tan (- theta?

The law of Tangent which is also called as tangent formula or tangent rule is the ratio of the sine of the angle to the cos of the angle. Tan Θ = Opposite / Adjacent.

## What is a reciprocal trig function?

There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). … Cosecant theta is 1 over y and cotangent is x over y.

## What is a reciprocal identity?

The reciprocal means flipping the numbers. … 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 is the reciprocal of Tanθ?

The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

## Is the value of sin 60?

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

## Whats the opposite of Cos?

Sine, Cosine and TangentSine Function:sin(θ) = Opposite / HypotenuseCosine Function:cos(θ) = Adjacent / HypotenuseTangent Function:tan(θ) = Opposite / Adjacent

## What is sine formula?

= 0.500. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions. In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as ‘sin’ without the ‘e’:

## What does a sine curve look like?

The domain of the sine function As you drag the point A around notice that after a full rotation about B, the graph shape repeats. The shape of the sine curve is the same for each full rotation of the angle and so the function is called ‘periodic’. The period of the function is 360° or 2π radians.

## What does 2 pi n mean?

– GEdgar Dec 5 ’16 at 21:15. Think of the unit circle plotted on a Cartesian graph. x=cosθ, so cosθ≥0 for all values on and to the right of the y-axis. 2nπ comes from the fact that 2π is the period of the cosine function.

## 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.

## What is the sin of angle B?

Example 2 Find the side b The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.

## 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.
