# Quick Answer: What is cosecant?

## What is Cosecant equal to?

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. = tan 5π 4. tan x = −∞.

## What is Cosecant the inverse of?

The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

## What is Cosecant on a calculator?

The calculator does not have built-in secant, cosecant, or cotangent functions. You must calculate these functions by using the appropriate reciprocal identities.

## What is a Cosecant function?

The cosecant function is the reciprocal of the sine function. The sine function is the opposite side divided by the hypotenuse, so the cosecant function is the hypotenuse divided by the opposite side. These functions give a relationship or ratio between the sides based on the given angles.

## 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. 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.

## What is sin equal to?

Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram).

## What is the inverse of tan?

So, the inverse of a tangent is called the arctangent (or arctan for short).

## Is Tan 1 the same as cot?

Using the tan 1 x convention may lead to confusion about the difference between arctangent and cotangent. It turns out that arctan and cot are really separate things: cot (x) = 1 / tan (x), so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse.

## What is inverse secant equal to?

The inverse function of secant. Basic idea: To find sec 1 2, we ask “what angle has secant equal to 2?” The answer is 60°. As a result we say that sec 1 2 = 60°. In radians this is sec 1 2 = π/3.

## What is arc sin?

The arcsin function is the inverse of the sine function. It returns the angle whose sine is a given number. Means: The angle whose sin is 0.5 is 30 degrees.

## How do you evaluate CSC?

The cosecant of an angle in a right triangle is a relationship found by dividing the length of the hypotenuse by the length of the side opposite to the given angle. This is the reciprocal of the sine function.

## How do you find Cotangent on a calculator?

The formula for determining the tangent is the opposite side divided by the adjacent side of a triangle. So, since the cotangent is the reciprocal, then the formula for determining the cotangent is the adjacent side divided by the opposite side of the triangle.

## What is Cosec formula?

The relationship between the measures of an angle and the length is called trigonometric ratios. We have hypotenuse, base, and perpendicular in a right angle triangle. And using these three sides, we can find the value of all the six functions. Cosec = Hypotenuse / Perpendicular. Cot = Base / Perpendicular.

## How do you use Cosecant?

In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just ‘ csc ‘. Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.

## What are the 3 trigonometric identities?

The three main functions in trigonometry are Sine, Cosine and Tangent.
