## Is CSC sin or cos?

The cosecant is the reciprocal of the sine.

The secant is the reciprocal of the cosine.

The cotangent is the reciprocal of the tangent..

## What is CSC Trig?

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’. They can be easily replaced with derivations of the more common three: sin, cos and tan. …

## Is CSC positive or negative?

Signs of Angles in Quadrants In the second quadrant, only sine and cosecant (the reciprocal of sine) are positive. In the third quadrant, only tangent and cotangent are positive. Finally, in the fourth quadrant, only cosine and secant are positive.

## How do you find the exact value of CSC?

Trigonometry Examples Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of csc(60) is 2√3 . Multiply 2√3 by √3√3 . Combine and simplify the denominator.

## Is arcsec the same as 1 Arccos?

Actually it’s: arcsec(x)=arccos(1/x).

## What is the reciprocal of CSC?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

## Is CSC a sin?

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 are the six trigonometric functions?

These functions often appear in the solution of differential equations and functional equations. The trigonometric functions include the following 6 functions: sine, cosine, tangent, cotangent, secant, and cosecant.

## 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.
