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?

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?
