Why is sin0 not 1?
Answer) Basically, sin(x) can be defined as (opposite side of a triangle/ adjacent side of a triangle). If the value of the angle between the hypotenuse and the adjacent side is equal to zero, then there is no opposite side, which means the length of the opposite is zero. Hence, the ratio is equal to zero.
What does cos0 0 mean?
Once the angle measurement hits 0, the hypotenuse and the adjacent side will lie perfectly on top of each other, falling into a 1-to-1 ratio. Thus, the cosine of 0 is equal to 1.
What is the value of sin0 cos0?

| sin | 0 | 1 |
| cos | 1 | 0 |
Are sin and cos ever both 0?
The inequality has no solution when sin x or cos x take the value 0. This happens at intervals of 90°. The solutions of the equation sin x ∙ cos x = 0 on the interval 0 x < 2 are therefore 0, /2, and 3 /2 (0°, 90°, 180° and 270°).
What is cos0 value?
1
Cos 0 Degree Value. Cos 0 equals to 1 (Cos 0 = 1). In other words, the value of Cos 0 is 1.
How do you find 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 θ=0 , the rightmost point, the coordinate pair is (1, 0). The y-coordinate is 0, so sin(0)=0 .
Which trigonometric function has a value of 0?
Sine Definition In Terms of Sin 0
| Angle | 00 | 2700 |

| Sin A | 0 | -1 |
| Cos A | 1 | 0 |
| Tan A | 0 | Undefined |
Which trig functions are not defined at 0?
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.
Why is cos(0) = 1?
When x = 0, adjacent side length=hypotenuse length. Therefore, cos(0) = 1. Consider a series of triangles with the base angle gradually approaching the value 0. We can use the Unit Circle to prove this to ourselves: At 0 degrees, the angle intercepts the Unit Circle at the coordinate (1,0). The coordinates are the trig values.
What is the value of sin 0 at 0 degrees?
At 0 degrees, the angle intercepts the Unit Circle at the coordinate (1,0). The coordinates are the trig values. The x-coordinate is the cos value and the y-coordinate is the sin value.
What is the value of cos 0° and sin 0°?
Cos 0° =1 & sin0° =0, very simple explanation is: In any right triangle, try to make its acute angle =0° by rotating terminal side (hypotenuse) towards its initial side ( base). You may notice that while doing so, perpendicular goes on decreasing & finally it becomes zero. But hypotenuse & base become equal.
What is the cosine of a zero angle?
Cosine of an angle = base/hypotenuse. Since the angle is zero, the length of the base is the same as the hypotenuse so cos 0 = 1. On the other hand sine of an angle is opposite/ hypotenuse. Since the angle is zero, the length of the opposite side is zero and the hypotenuse is the same as the base, hence sin 0 = 0/ Assume angle BCA to be x.
