# Why is sin0 equal to 0?

## Why is sin0 equal to 0?

On the unit circle, the x-coordinate at each position is the cosine of the given angle, and the y-coordinate is the sine. For u03b80 , the rightmost point, the coordinate pair is (1, 0). The y-coordinate is 0, so sin(0)0 .

## Why is sin0 0 but cos0 1?

cosine of an angle base/hypotenuse. In case of cos(0)1; base hypotenuse 1; It isn’t possible, because if base hypotenuse, then height 0 (by Pythagorean theorem – Wikipedia ) , which is not possible (height of triangle can ‘t be 0). Hence, actually the value of cos(0) is 0.9999 and we take this as 1.

## What does sin0 0 mean?

Sin 0 signifies that the value of x coordinate is equal to 1 and the value of y coordinate is equal to 0, that is the coordinates (x, y) is (1, 0) which means that the value of When we place the values in sin ratio for u03b80xb0 , substituting perpendicular side 1 and hypotenuse 0, We get, Sin 0u2070 0/1. Or.

## What is the exact value of sin0?

cosine of an angle base/hypotenuse. In case of cos(0)1; base hypotenuse 1; It isn’t possible, because if base hypotenuse, then height 0 (by Pythagorean theorem – Wikipedia ) , which is not possible (height of triangle can ‘t be 0). Hence, actually the value of cos(0) is 0.9999 and we take this as 1.

## How does Cos 90 equal zero?

The exact value of sin(0) is 0 .

## Why is sin0 not 1?

On the unit circle, the x-coordinate at each position is the cosine of the given angle, and the y-coordinate is the sine. For u03b80 , the rightmost point, the coordinate pair is (1, 0). The y-coordinate is 0, so sin(0)0 .

## Why is cos0 equal to 1?

## Is Sin0 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 trigonometry value?

Trigonometry values are all about the study of standard angles for a given triangle with respect to trigonometric ratios. The word ‘trigon’ means triangle and ‘metron’ means ‘measurement’. It’s one of the major concepts and part of geometry, where the relationship between angles and sides of a triangle is explained.

## What is sin to the 0?

## 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 x0,u03c0, and 2u03c0 in the domain [0,2u03c0] , and continues to cross the x-axis at every integer multiple of u03c0 .

## What is the 0 in sin0?

On the unit circle, the x-coordinate at each position is the cosine of the given angle, and the y-coordinate is the sine. For u03b80 , the rightmost point, the coordinate pair is (1, 0). The y-coordinate is 0, so sin(0)0 .

## What does sin0 mean in math?

Sin 0 signifies that the value of x coordinate is 1 and the value of y coordinate is 0,i.e. (x,y) is (1,0). That means the value of the opposite side or perpendicular is zero and the value of hypotenuse is 1.

## What is sin0 value?

Sin 0 degrees is the value of sine trigonometric function for an angle equal to 0 degrees. The value of sin 0xb0 is 0

## How do you find the value of sin0?

Sin 0 degrees is the value of sine trigonometric function for an angle equal to 0 degrees. The value of sin 0xb0 is 0

## In what condition does cosine function is equal to 0?

cos x 0, when x xb1u03c0/2, xb13u03c0/2, xb15u03c0/2, It means that cos x vanishes when x is an odd multiple of u03c0/2. So, cos x 0 implies x (2n + 1)u03c0/2 , where n takes the value of any integer. For a triangle, ABC having the sides a, b, and c opposite the angles A, B, and C, the cosine law is defined.

## Why TAN 90 is undefined?

tan90u2218 is undefined because you can’t divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined.
