# What is the ratio for sine

What is the ratio for sine: Definition of Sine Ratio World’s most popular and ratio of the length of the opposite side divided by the length of the hypotenuse.

Also, can the sine of an angle ever be equal to 2?

Sine of any angle 2. cannot be , as you may know, sin90=1,u can conclude that sin180=2. But 180 degree can’t be angle of triangle, hope it helps!

Here, what are the 3 triple ratios?

There are three basic trigonometric ratios: sine, cosine, and tangent . Given a right triangle, you can find the sine (or cosine, or tangent) of any non-90° angles.

Also to know why sine is a ratio? And since we’re just talking about the sine, you can miss the sine because it’s the ratio of the opposite of the hypotenuse to sine . The cosine is the ratio of the adjacent to the hypotenuse and the tangent is the ratio of the opposite to the adjacent.

What is the ratio of cosecant?

We know that cosecant is the reciprocal of the sine . Since sine is the ratio of the opposite to the hypotenuse, cosecant is the inverse ratio of the hypotenuse.

#### Can the cosine of an angle ever be equal to 1?

Originally Answered: Can the value of cosine be greater than 1? Consider a right angled triangle. Since the adjacent side cannot be greater than the hypotenuse, the cosine of an angle is 1 . cannot be more than .

#### Is it possible for the sine of an angle to be equal?

Sal shows that the sine of any angle is equal to the cosine of its complementary angle .

#### What is the relation between sine cosine and tangent?

When the ratio includes sides: opposite hypotenuse it is called a sine. When the ratio includes sides: the adjacent hypotenuse is called a cosine. When the ratio includes sides: opposite adjacent it is called a tangent . Ratios are always found in terms of angles and they represent a value.

#### What is SOH CAH TOA?

“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent. Equals to the opposite of the hypotenuse, the cosine equals to the adjacent on the hypotenuse, and the tangent equals to the opposite on the adjacent, (1) (2) (3) Other mnemonics include.

#### What is sin A and sin B?

In simple words, it states that the ratio of the length of a side of a triangle and the sine of the angle opposite to that side is the same for all the sides and angles of a given triangle. ABC is an obtuse triangle with sides a,b and c, then a sinA=bsinB=csinC .

#### What are the six trigonometric ratios of a right angled triangle?

There are six triple ratios for any right triangle: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot) .

#### What is the correct formula for sine ratio?

Use the sine ratio to calculate angles and sides (sin = be)

One of the trigonometric ratios is the sine ratio. It is the side opposite to the hypotenuse of right angled triangles.

#### What is the sine ratio of 74?

sine cosine tangent chart

#### What is the sine ratio for F?

The final answer is 12 / 13 .

#### What are the six triple ratios?

Sal finds all six trigonometric ratios ( sine, cosine, tangent, secant, cosecant, and cotangent ) of angles in a given right-angled triangle.

#### Which angle has sine 1 2?

sine and cosine for particular common angles

#### Can a sign be negative?

This only works for angles between 0 and 90 degrees . This definition allows the sine to be taken as negative because the vertical co-ordinates in the two lower quadrants will be negative.

#### Why can tan be greater than 1?

Why can the tangent function be greater than 1, but the sine and cosine functions cannot . Regardless of which angle you evaluate the tangent, cosine, or sine for, you can always think of it as the ratio of two sides of a right triangle. … For the tangent function, you can divide the opposite side by the adjacent side.

#### Why is the sign called a sign?

The word sign comes from the Latin sinus, bosom, as early translators mistook the Arabic word for chord and thought it to be the Arabic word for bosom . The “co-” prefix in cosine and cotangent just stands for co-angle, complementary angle. The cosine of an angle is the sine of its supplementary angle.

#### Is the tangent sin at COS?

Each of these functions is somehow derived from sine and cosine. The tangent to x is defined as its sine divided by its cosine: tan x = sin x because x . … secant 1 of x is divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined as 1 divided by the sine of x: csc x = 1 sin x .

#### What exactly is Sin Cos and Tan?

The sine (often abbreviated “sin”) of one of the angles of a right triangle is the ratio of the length of the side of the triangle opposite the angle to the length of the hypotenuse of the triangle. … SOH → sin = “opposite” / “hypotenuse” CAH → cos = “adjacent” / “hypox” TOA → tan = “opposite” ” / “adjacent”

#### Is SOH CAH TOA only for right angled triangles?

Question: Is Sohkahtoa only for right angled triangles? A: Yes, this only applies to right angled triangles . If we have an oblique triangle, we cannot assume that these triangle ratios will work. … a: they are the hypotenuse of a right triangle always opposite the 90-degree angle, and the longest side.

#### How do I know if I have SOH CAH TOA?

They are often shortened to sin, cos and tan. The calculation is simple.
One side of a right triangle is divided by the other side
we just need to know which sides are which, and that’s where “sohkahtoa” helps.
sine, cosine and tangent.

#### How do you calculate sin?

For any angle in any right triangle:

1. Sine of angle = length of opposite side. The length of the hypotenuse.
2. Cosine of angle = length of adjacent side. The length of the hypotenuse.
3. Tangent of angle = length of opposite side. armpit length.
