## What is the value of sin 0 upon 0?

1

thus sin(0) / 0 = 1.

**What is the sine value of 0?**

The exact value of sin(0) is 0 .

**Why does sin equal zero?**

Draw a right angled triangle. The sine of any other angle θ, except the 90˚ one is the ratio of the opposite side to the hypotenuse. Let now θ tend to zero and the side opposite θ also diminishes to zero. Hence sin0 = 0.

### Is sin a real number?

Note that the domain of the function y=sin(x) ) is all real numbers (sine is defined for any angle measure), the range is −1≤y≤1 . The graph of the cosine function looks like this: The domain of the function y=cos(x) is all real numbers (cosine is defined for any angle measure), the range is −1≤y≤1 .

**Which trig functions are not defined at 0?**

First, the the secant, cosecant, and cotangent functions are the reciprocals of the cosine, sine, and tangent functions, respectively. Second, there is no value for which the cosine and sine functions are undefined. This is because r is the distant from the origin to the point (x,y) ≠ (0,0) on the terminal ray.

**Where is Sinx 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.

## What is sin value?

As can be seen from the figure, sine has a value of 0 at 0° and a value of 1 at 90°. Cosine follows the opposite pattern; this is because sine and cosine are cofunctions (described later). The other commonly used angles are 30° ( ), 45° ( ), 60° ( ) and their respective multiples.

**What is the value of sin 1 0?**

sin−1(0)=nπ where n is an integer.

**What value of sin is?**

Sin 0 Value-

Name | Abbreviation | Relation |
---|---|---|

Sine | Sin | Sin(θ) = Opposite/Hypotenuse |

CoSine | Cos | Cos(θ) = Adjacent/Hypotenuse |

Tangent | Tan | Tan(θ) = Opposite/Adjacent |

### Why is the domain of sin all real numbers?

As we understand, the sin(x) is defined as the opposite divided by the hypotenuse. For this unit circle, at any point, sin(x) is equal to opposite / 1. This measure of opposite can be defined for all the points on the circle, indicating that the angle x can take any value. So, the domain of sin(x) is all real numbers.
