# FAQ: What Is Csc In Math?

## Is CSC sin or cos?

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 does Cosecant mean?

1: a trigonometric function that for an acute angle is the ratio between the hypotenuse of a right triangle of which the angle is considered part and the leg opposite the angle.

## 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. The two can be confused since arcsin(x) is often denoted as sin ^- 1 (x) and x^- 1 is 1 /x.

## What is the opposite of CSC?

Cosecant Function: csc (θ) = Hypotenuse / Opposite. Secant Function: sec(θ) = Hypotenuse / Adjacent.

## What is Arccsc equal to?

arccsc (arc cosecant) The inverse of the cosecant function. Also written arc-cosecant, arc-cosecx, acsc, cosec1, or csc1. The value of the arccsc function of any argument is an angle in radians whose cosecant function equals the given argument, that is, y = csc1x if and only if x = cosec(y) for – /2 < y < /2 and y.

## What is CSC formula?

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 ‘. csc. x. =

## Where is CSC not defined?

The cosecant formula is not defined everywhere. For angles of the form x = k·180° for k an integer, there is no csc x.

## What sine means?

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).

## What is sin 1 called?

The symbol for inverse sine is sin 1, or sometimes arcsin.

## Is sin 1 the same as 1 sin?

Common Calculus Mistakes Example: Derivative of inverse sine. The notation sin 1 (x) has been misunderstood to mean 1 / sin (x). So sin 1 (x) means the inverse sine of x, that is, the function that undoes the sine function. It is not equal to 1 / sin (x).

## What is the inverse of sine called?

Inverse Sine: If you know the opposite side of an angle and the hypotenuse in a right triangle, you can use inverse sine to find the measure of the angle. Inverse sine is also called arcsine and is labeled begin{align*} sin ^{ -1}end{align*} or arcsin.
