sin 2π = sin 0° = y-coordinate of (1, 0) = 0. Hence, sin 2π = 0.

## What is the sine value of 2pie 3?

The value of sin 2pi/3 is 0.8660254. . .. Sin 2pi/3 radians in degrees is written as sin ((2π/3) × 180°/π), i.e., sin (120°).

## What is 2pie?

An angle measured in radians is the ratio of the arc length of a circle subtended by that angle, divided by the radius of the circle. … Since 90° = π / 2 radians, to four significant figures, one radian equals 180°/ π = 57.30°. There are 2π radians in a full circle. (So 2π radians should equal 360°.

## How do you find the value of sin 2pi?

Sin 2π = Sin ( 360° + 0) = Sin 0° = 0. Sin 2π = Sin ( 360° + 0) = Sin 0° = 0.

## Is sin 2pi undefined?

Since sin(2π)=0 and 10 is undefined or infinity, we can determine that csc(2π) = infinity or undefined. Hope this helps.

## How do you get Cos 2pie 3?

The value of cos 2pi/3 can be calculated by constructing an angle of 2π/3 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of cos 2pi/3 is equal to the x-coordinate (-0.5). ∴ cos 2pi/3 = -0.5.

## What is the exact value of sin 8pi 3?

The exact value of sin(π3) sin ( π 3 ) is √32 .

## What is the value of 2 pi into the palette?

It is twice the ratio of circle perimeter to its diameter. Defination of π- It is ratio of circle perimeter to its diameter . Short answer: 2 pi is approximately 6.28318530718, with ten decimals.

## What is pie in number?

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. … Measure the circumference with a ruler.

## What is 2pie circle?

Anyway, it turns out that π/2 Radians = 90°, π Radians = 180°, and, therefore, 2π Radians = 360°, which is to say, 2π Radians = the circumference of ANY circle, regardless of the radius, or any other size-parameter of a circle.

## What degree is 2pi?

Thus 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π ≈ 57.295779513082320876 degrees.

## Is the value of sin 45?

The value of Sin 45 degree in decimal form is 0.7071067812.

## What is the value of sin?

The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio.

## Where is sine undefined?

Trigonometric functions are undefined when they represent fractions with denominators equal to zero. Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to 0. The value of sin (0) is 0, so the cosecant of 0 must be undefined.

## Where does sin equal zero?

sinx is known as a periodic function that oscillates at regular intervals. It crosses the x-axis (i.e. it is 0 ) at x=0,π, and 2π in the domain [0,2π] , and continues to cross the x-axis at every integer multiple of π .

## How do you write cosecant?

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’.
