## What is sin2theta? ## What is sin90 value?

The exact value of sin 90 degrees is equal to 1.

## What is the value of sin 25?

Sin 25 degrees is the value of sine trigonometric function for an angle equal to 25 degrees. The value of sin 25° is 0.4226 (approx).

## How do you solve cos 25?

⇒ 25 degrees = 25° × (π/180°) rad = 5π/36 or 0.4363 . . . Explanation: For cos 25 degrees, the angle 25° lies between 0° and 90° (First Quadrant). Since cosine function is positive in the first quadrant, thus cos 25° value = 0.9063077. . .

## What is value of sin30?

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.Jul 2, 2020

## What is the value of sin 20?

Sin 20 degrees is the value of sine trigonometric function for an angle equal to 20 degrees. The value of sin 20° is 0.342 (approx).

## How do you find the value of sin35?

The value of sin 35° is equal to the y-coordinate (0.5736). ∴ sin 35° = 0.5736.

## How do you find cot 25?

Using trigonometric identities, we can write cot 25° in terms of sin 25° as, cot(25°) = √(1 - sin²(25°))/sin 25° .

## How do you find cosine of 35 degrees?

The value of cos 35 degrees can be calculated by constructing an angle of 35° with the x-axis, and then finding the coordinates of the corresponding point (0.8192, 0.5736) on the unit circle. The value of cos 35° is equal to the x-coordinate (0.8192). ∴ cos 35° = 0.8192.

Note: Since 30° lies in the 1st Quadrant, the final value of sin 30° will be positive. We can use trigonometric identities to represent sin 30° as, sin(180° - 30°) = sin 150°  ### What is the value of cot45?

Cot 45 degrees is the value of cotangent trigonometric function for an angle equal to 45 degrees. The value of cot 45° is 1.

### How do you find the value of sin 18?

How to Find the Value of Sin 18 Degrees? The value of sin 18 degrees can be calculated by constructing an angle of 18° with the x-axis, and then finding the coordinates of the corresponding point (0.9511, 0.309) on the unit circle. The value of sin 18° is equal to the y-coordinate (0.309). ∴ sin 18° = 0.309.
