## Is Arccos the same as SEC?

Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan.

Note, sec x is not the same as cos-1x (sometimes written as arccos x)..

## What does CSC graph look like?

The vertical asymptotes of cosecant drawn on the graph of sine. … The cosecant goes down to the top of the sine curve and up to the bottom of the sine curve. After using the asymptotes and reciprocal as guides to sketch the cosecant curve, you can erase those extra lines, leaving just y = csc x.

## 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.

## What is CSC equal to?

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 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.

## How do you find CSC in trigonometry?

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 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.

## How do you remember CSC SEC and cot?

r/learnmath Easiest way to memorize the sin tan cos csc sec and cot functions? SOH CAH TOA is the usual acronym–Sine Opposite Hypotenuse, Cosine Adjacent Hpyotenuse, Tangent Opposite Adjacent. And then secant/cosecant/cotangent are the same, where secant goes with COsine and COsecant goes with sine.

## Does sin 1 equal 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 cot stand for in math?

cotangentThe short name for cotangent. It is the length of the adjacent side divided by the length of the side opposite the angle in a right-angled triangle. cot(θ) = adjacent / opposite. (Note: the tangent function tan(θ) = opposite / adjacent)

## Is 1 tan the same as cot?

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)
