Bạn đang xem: Find value of sin 6 degrees

. Sin 6 degrees in radians is written as sin (6° × π/180°), i.e., sin (π/30) or sin (0.104719. . .). In this article, we will discuss the methods to lớn find the value of sin 6 degrees with examples.

Sin 6°: 0.1045284. . .Sin (-6 degrees): -0.1045284. . .Sin 6° in radians: sin (π/30) or sin (0.1047197 . . .)

What is the Value of Sin 6 Degrees?

We know, using degree khổng lồ radian conversion, θ in radians = θ in degrees × (pi/180°)⇒ 6 degrees = 6° × (π/180°) rad = π/30 or 0.1047 . . .∴ sin 6° = sin(0.1047) = 0.1045284. . .

Explanation:

For sin 6 degrees, the angle 6° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 6° value = 0.1045284. . .Since the sine function is a periodic function, we can represent sin 6° as, sin 6 degrees = sin(6° + n × 360°), n ∈ Z.⇒ sin 6° = sin 366° = sin 726°, & so on.Note: Since, sine is an odd function, the value of sin(-6°) = -sin(6°).

Methods to lớn Find Value of Sin 6 Degrees

The sine function is positive in the 1st quadrant. The value of sin 6° is given as 0.10452. . .. We can find the value of sin 6 degrees by:

Using Trigonometric FunctionsUsing Unit Circle

Sin 6° in Terms of Trigonometric Functions

Using trigonometry formulas, we can represent the sin 6 degrees as:

± √(1-cos²(6°))± chảy 6°/√(1 + tan²(6°))± 1/√(1 + cot²(6°))± √(sec²(6°) - 1)/sec 6°1/cosec 6°

Note: Since 6° lies in the 1st Quadrant, the final value of sin 6° will be positive.

We can use trigonometric identities lớn represent sin 6° as,

sin(180° - 6°) = sin 174°-sin(180° + 6°) = -sin 186°cos(90° - 6°) = cos 84°-cos(90° + 6°) = -cos 96°

Sin 6 Degrees Using Unit Circle

*

To find the value of sin 6 degrees using the unit circle:

Rotate ‘r’ anticlockwise to form a 6° angle with the positive x-axis.The sin of 6 degrees equals the y-coordinate(0.1045) of the point of intersection (0.9945, 0.1045) of unit circle and r.

Hence the value of sin 6° = y = 0.1045 (approx)
