# Quick Answer: What Is Sin1 Value?

## Is the value of sin 30 degree?

The value of sin 30 degrees is 0.5.

Sin 30 is also written as sin π/6, in radians.

The trigonometric function also called as an angle function relates the angles of a triangle to the length of its sides..

## Is the value of sin 60?

From the above equations, we get sin 60 degrees exact value as √3/2.

## What is COS 1 in radians?

If it was in radian, Cos(1 rad) = 0.54030230586. You can easily find the answer by googling it.

## What is the formula for cos 3x?

Prove the following identity: cos 3x = 4 cos^3x – 3cosx Here is what I did and where I’m stuck: cos 3x = cos (2x+x) = (cos 2x)(cos x) – (sin 2x)(sin x) = (2 cos^2x-1)(cos x) – [(2 sinx)(cosx)](sinx) I’m not sure how you distribute this.

## Which is greater sin1 sin2 and sin3 sin4?

Originally Answered: Which is greater: sin1, sin2, or sin3? We know , Sine function increases from 0 to 1 in the interval [ 0 , 90° or pi/2] . Hence , in degrees , sin 3° will be greater then other two. … Hence , Sin 2 will be greater than sin 1 as sin 2 = Sin 114° = Sin ( 180° – 66°) = Sin (66°).

## Why is tan 90 undefined?

At 90 degrees we must say that the tangent is undefined (und), because when you divide the leg opposite by the leg adjacent you cannot divide by zero. In the third quadrant the hypotenuse extended will now meet the tangent line above the x-axis and is now positive again.

## What is sin theta formula?

If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side.

## What is the sin of 60 in radians?

To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° or 2π radians. The exact value of sin(60) is √32 .

## What is the exact value of CSC 60?

The exact value of csc(60°) csc ( 60 ° ) is 2√3 .

## Which is greater sin1 or sin1 degree?

i.e. sin 1 is greater than sin 1 degree.

## How do you convert angles to radians?

To convert from degrees to radians, multiply the degrees by π180° radians .

## How do you find the value of sin 90?

Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. Therefore, sin 90 degree equals to the fractional value of 1/ 1….Derivation to Find the Value of Sin 90 Degrees\sin x=\frac{1}{\csc x}\sin^{2}x+\cos ^{2}x=1.\sin (-x)=-\sin x.Sin 2x = 2 sin x cos x.

## What is this called θ?

Theta (uppercase Θ, lowercase θ) is the eighth letter of the Greek alphabet, derived from the Phoenician letter Teth. In the system of Greek numerals it has a value of 9. … In American English, the name of the letter is commonly pronounced [θeɪɾə].

## How do you find sin 75?

Answer. Sin(A+B) = Sin A Cos B + Cos A Sin B. Sin 75 = Sin ( 45 + 30) = Sin 45 Cos 30 + Cos 45 Sin 30. Sin 75 = (1 / √2) ( √3 / 2) + (1 / √2) ( 1 / 2) = [ √3 + 1] / 2√2.

## How do you find Theta?

To find the angle theta in degrees in a right triangle if the tanθ = 1.7, follow these steps:Isolate the trig function on one side and move everything else to the other. This step is done already. … Isolate the variable. … Solve the simplified equation.

## What does sin0 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.

## What is the value of TAN 60 )?

Answer and Explanation: The exact value of tan(60°) is √(3).
