What does sin 0 mean?

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.

Why is sin 0 equal to?

The value of sin 0° is equal to the y-coordinate (0). ∴ sin 0° = 0.

What is sin 0 degree equal to?

The value of sin0o is 0.

What does sin θ 0 mean?

sin θ < 0, means the values of sin must be negative. cos θ > 0, means the values of cos must be positive.

Why is sin 0 equal to 1?

So technically according to the unit circle the coordinates of 0 degrees are (1,0) so cos is the x value in the coordinate which would be 1 and sin is the y value which is 0.

What does the sine of an angle actually mean

Is sin 0 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 value of cos is 0?

The value of cos 0 is 1.

What does θ mean in trigonometry?

The Greek letter θ (theta) is used in math as a variable to represent a measured angle. For example, the symbol theta appears in the three main trigonometric functions: sine, cosine, and tangent as the input variable. cos(θ)

What is sin equal to?

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse whereas the cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse. Sin θ = Opposite side/Hypotenuse.

Can sin theta be zero?

Therefore, General Solution of sinθ=0 is nπ

What is sin divided by 0?

thus sin(0) / 0 = 1.

Is sin 0 at pi?

What is the value of sin pi? In trigonometry, we use pi (π) for 180 degrees to represent the angle in radians. Hence, sin π is equal to sin 180 or sin π = 0.

Is sin of infinity zero?

Also, ∞ is undefined thus, sin(∞) and cos(∞) cannot have exact defined values. However, sin x and cos x are periodic functions having a periodicity of (2π). Thus, the value of sin and cos infinity lies between -1 to 1. There are no exact values defined for them.

Is sin 0 an even function?

Sine is an odd function, and cosine is an even function. You may not have come across these adjectives “odd” and “even” when applied to functions, but it's important to know them.

Is sine always 1?

Short answer: The sine function takes values from −1 to 1 because that's just the nature of the function.

How hard is trigonometry?

In general, trigonometry is considered hard, especially when right triangle numerals are given as word problems. However, an exact answer to this question depends upon a number of factors as some people find trigonometry hard while others think it to be relatively easy.

How is the sine rule?

The law of sine is explained in detail as follow: In a triangle, side “a” divided by the sine of angle A is equal to the side “b” divided by the sine of angle B is equal to the side “c” divided by the sine of angle C.

When sin theta is equal to 1?

Hence, the general solution of sin θ = 1 is θ = (4n + 1)π2, n ∈ Z. Therefore, either, 2 sin x + 3 = 0 ⇒ sin x = - 32, Which is impossible since the numerical value of sin x cannot be greater than 1. We know that the general solution of sin θ = 1 is θ = (4n + 1)π2, n ∈ Z.

What does sin 1 0 mean?

sin−1(0)=nπ where n is an integer - this allows us to express not just 0 degrees but also π,2π,3π,−π,−2π and so on.
