# What Is The CSC In Math?

## What is CSC equal to?

The tangent of x is defined to be its sine divided by its cosine: …

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 Arctan equal to?

Arctan definition The arctangent of x is defined as the inverse tangent function of x when x is real (x∈ℝ).

## What are the 9 trig identities?

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

## Is COT the same as 1 tan?

tan x−1, sometimes interpreted as (tan(x))−1 = 1tan(x) = cot(x) or cotangent of x, the multiplicative inverse (or reciprocal) of the trigonometric function tangent (see above for ambiguity)

## What is CSC SEC and cot?

cotangent(q) = adj/opp. The functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot). It is often simpler to memorize the the trig functions in terms of only sine and cosine: sine(q) = opp/hyp. csc(q) = 1/sin(q)

## Is sin 1 the same as CSC?

Sine of an angle is the side of the triangle that does not touch the angle divided by the hypotenuse. … 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 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 find the Cosecant?

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.

## What is the inverse of sine called?

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

## How do you express tan in terms of sin?

To rewrite the sine function in terms of tangent, follow these steps:Start with the ratio identity involving sine, cosine, and tangent, and multiply each side by cosine to get the sine alone on the left.Replace cosine with its reciprocal function.Solve the Pythagorean identity tan2θ + 1 = sec2θ for secant.More items…

## How do you do CSC 2 on a calculator?

If you want to get sec2(0), you should first notice that sec2(0)=1cos2(0). I would, then, first get cos(0), and then press the x^2 and 1/x buttons.

## What is CSC in terms of sin?

cosecant. The cosecant is the reciprocal of the sine. csc ⁡ ( A ) = 1 sin ⁡ ( A ) \csc(A)=\dfrac{1}{\sin(A)} csc(A)=sin(A)1. secant. The secant is the reciprocal of the cosine.

## What is CSC on a calculator?

Cosecant (csc) – Trigonometry function 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’. … In fact, most calculators have no button for them, and software function libraries do not include them.

## What are the six trigonometric functions?

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