Why is cosecant the reciprocal of sine?

We know that the cosecant is the reciprocal of the sine. Since sine is the ratio of the opposite to the hypotenuse, cosecant is the ratio of the hypotenuse to the opposite.

How are csc and sin related?

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 the reciprocal of cosecant?

The reciprocal of the cosecant function is the sine function itself. The product of the reciprocal of sine and the sine function is always equal to 1. Reciprocal of sine is written as cosec x = 1/sin x.

Which is the same for both the sine and cosecant function?

So, the cosecant has the same period as the sine function of 2pi, the secant has the same period as the cosine function of 2pi, and the cotangent has the same period as the tangent function of pi.

Why is Secant the reciprocal of Cosine, and Cosecant the reciprocal of Sine?



Is reciprocal the same as inverse?

“Inverse” and “reciprocal” are terms often used in mathematics. “Inverse” means “opposite.” “Reciprocal” means “equality,” and it is also called the multiplicative inverse.

Do sin and csc cancel?

The reciprocal of the sine function is the cosecant function. The following is a valid identity for all x in the domain of the cosecant function. The arcsine function is the inverse function for the sine function on the interval . So they "cancel" each other under composition of functions, as follows.

Is secant the reciprocal of cosine?

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).

What is the purpose of reciprocal trig functions?

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 , ⁡ , ⁡ and ⁡ by taking the reciprocal of both sides.

What is the purpose of Secant Cosecant and Cotangent?

Secant is the reciprocal of cosine. Cotangent is the reciprocal of tangent. When solving right triangles the three main identities are traditionally used. However, the reciprocal functions (secant, cosecant and cotangent) can be helpful in solving trig equations and simplifying trig identities.

Does csc equal sin 1?

It is important to note that there is a big difference between the reciprocal value csc θ and sin-1x. The cosecant function means 1/sin θ, while the second involves finding an angle whose sine is x.

Why do reciprocals work?

Reciprocal: A number that has a relationship with another number such that their product is 1. This means that, when you take a number such as 5 and then multiply it by its reciprocal, you will end up with an answer of 1.

What does reciprocal mean in math?

In Maths, reciprocal is simply defined as the inverse of a value or a number. If n is a real number, then its reciprocal will be 1/n. It means that we have to convert the number to the upside-down form. For example, the reciprocal of 9 is 1 divided by 9, i.e. 1/9.

Does cosecant have an amplitude?

The period of both secant and cosecant is 2π like sine and cosine. There is no amplitude for secant and cosecant, but there is a vertical stretch that is used instead.
