What Is SEC CSC And Cot?

What is CSC math?

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..

Is cot the inverse of tan?

cot(x) = 1/tan(x) , so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse. arctan(x) is the angle whose tangent is x.

How is CSC calculated?

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’.

What is cot the inverse of?

The six important trigonometric ratios are sine, cosine, tangent, cosecant, secant and cotangent. The inverse of these functions is called the inverse trigonometric function. The inverse of the cotangent function is called inverse cotangent or arccot. It is denoted by cot-1x.

How do you remember CSC SEC and cot?

Here is how I always remembered them: 1+tan = sec –> 1 TAN man has a SECret. 1+cot = csc –> 1 man on a COT Cannot Sleep Comfortably.

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 the reciprocal of cot?

Secant is the reciprocal of cosine. … Cotangent is the reciprocal of tangent. Its abbreviation is cot.

Are cot and tan 1 the same?

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 the Cotangent?

In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length of the side opposite the angle. The abbreviation is cot. cot(θ) = adjacent / opposite. It is not commonly used, and is equal to 1/tangent.

Does sin go with CSC?

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 CSC equivalent to?

Cosecant FunctionCosecant, Secant and CotangentCosecant Function:csc(θ) = Hypotenuse / OppositeSecant Function:sec(θ) = Hypotenuse / AdjacentCotangent Function:cot(θ) = Adjacent / Opposite

Why Sine is called sine?

In mathematics, the sine is a trigonometric function of an angle. … The word “sine” (Latin “sinus”) comes from a Latin mistranslation by Robert of Chester of the Arabic jiba, which is a transliteration of the Sanskrit word for half the chord, jya-ardha.

Is sin 1 the same as Arcsin?

Strictly speaking, the symbol sin-1( ) or Arcsin( ) is used for the Arcsine function, the function that undoes the sine. … Think of the Arcsine as the principal arcsine. Restrict the domain to take this inverse function. A function can only be an inverse if it is 1-to-1 and undoes exactly the desired function.
