## How do you find the value of sin12?

The value of sin 12 degrees can be calculated by constructing an angle of 12° with the x-axis, and then finding the coordinates of the corresponding point (0.9781, 0.2079) on the unit circle. The value of sin 12° is equal to the y-coordinate (0.2079). ∴ sin 12° = 0.2079.

**How do you solve sin 70 degrees?**

The value of sin 70 degrees can be calculated by constructing an angle of 70° with the x-axis, and then finding the coordinates of the corresponding point (0.342, 0.9397) on the unit circle. The value of sin 70° is equal to the y-coordinate (0.9397). ∴ sin 70° = 0.9397.

**How do you solve sin 48 degrees?**

The value of sin 48 degrees can be calculated by constructing an angle of 48° with the x-axis, and then finding the coordinates of the corresponding point (0.6691, 0.7431) on the unit circle. The value of sin 48° is equal to the y-coordinate (0.7431). ∴ sin 48° = 0.7431.

### How do you find cos 70 without a calculator?

The value of cos 70° is equal to the x-coordinate (0.342). ∴ cos 70° = 0.342.

**How do you find the value of sin 32?**

⇒ 32 degrees = 32° × (π/180°) rad = 8π/45 or 0.5585 . . . Explanation: For sin 32 degrees, the angle 32° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 32° value = 0.5299192. . .

**What is the formula of degree?**

Now, since we know that Pi =180◦, we can use a general formula that is degrees x PI()/180 to get the radians figure. For example, 45◦ x PI()/180 is equal to 0.7854 radians. If we enter the formula =DEGREES(PI()), we will get the result as 180◦.

## How do you find the value of sin 8?

The value of sin 8° is equal to the y-coordinate (0.1392). ∴ sin 8° = 0.1392.

**How to find the exact value of sin without a calculator?**

Draw the angle, look for the reference angle. 2. Use special triangles or the unit circle. 3. Check the quadrant to determine the sign (+ or -). Calculating exact values of sin, cos, tan without a calculator. 1. Calculate the exact value of cos (-π/2)

**How do you find the exact value of sin cos cos tan?**

How to find the exact trigonometric values: sin, cos, tan? Draw the angle, look for the reference angle. Use special triangles or the unit circle. Check the quadrant to determine the sign (+ or -).

### What is the value of sin 30 at 90 degrees?

Which one is it? sin (30) =.5, and because we know the sine function is increasing up to 90 degrees the solution is approximately .34. So, what is the exact solution?

**What is the sine of an angle?**

Again, measure as accurately as you can. Now, as far as the opposite problem, let’s say you know that the sine of some angle is 0.86 or some other number (between -1 and 1). Can we find the angle without the calculator?
