Sin 930 Degrees
The value of sin 930 degrees is 0.5. Sin 930 degrees in radians is written as sin (930° × π/180°), i.e., sin (31π/6) or sin (16.231562. . .). In this article, we will discuss the methods to find the value of sin 930 degrees with examples.
 Sin 930°: 0.5
 Sin 930° in fraction: (1/2)
 Sin (930 degrees): 0.5
 Sin 930° in radians: sin (31π/6) or sin (16.2315620 . . .)
What is the Value of Sin 930 Degrees?
The value of sin 930 degrees in decimal is 0.5. Sin 930 degrees can also be expressed using the equivalent of the given angle (930 degrees) in radians (16.23156 . . .).
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 930 degrees = 930° × (π/180°) rad = 31π/6 or 16.2315 . . .
∴ sin 930° = sin(16.2315) = (1/2) or 0.5
Explanation:
For sin 930°, the angle 930° > 360°. Given the periodic property of the sine function, we can represent it as sin(930° mod 360°) = sin(210°). The angle 930°, coterminal to angle 210°, is located in the Third Quadrant(Quadrant III).
Since sine function is negative in the 3rd quadrant, thus sin 930 degrees value = (1/2) or 0.5
Similarly, sin 930° can also be written as, sin 930 degrees = (930° + n × 360°), n ∈ Z.
⇒ sin 930° = sin 1290° = sin 1650°, and so on.
Note: Since, sine is an odd function, the value of sin(930°) = sin(930°).
Methods to Find Value of Sin 930 Degrees
The sine function is negative in the 3rd quadrant. The value of sin 930° is given as 0.5. We can find the value of sin 930 degrees by:
 Using Unit Circle
 Using Trigonometric Functions
Sin 930 Degrees Using Unit Circle
To find the value of sin 930 degrees using the unit circle, represent 930° in the form (2 × 360°) + 210° [∵ 930°>360°] ∵ sine is a periodic function, sin 930° = sin 210°.
 Rotate ‘r’ anticlockwise to form a 210° or 930° angle with the positive xaxis.
 The sin of 930 degrees equals the ycoordinate(0.5) of the point of intersection (0.866, 0.5) of unit circle and r.
Hence the value of sin 930° = y = 0.5
Sin 930° in Terms of Trigonometric Functions
Using trigonometry formulas, we can represent the sin 930 degrees as:
 ± √(1cos²(930°))
 ± tan 930°/√(1 + tan²(930°))
 ± 1/√(1 + cot²(930°))
 ± √(sec²(930°)  1)/sec 930°
 1/cosec 930°
Note: Since 930° lies in the 3rd Quadrant, the final value of sin 930° will be negative.
We can use trigonometric identities to represent sin 930° as,
 sin(180°  930°) = sin(750°)
 sin(180° + 930°) = sin 1110°
 cos(90°  930°) = cos(840°)

Examples Using Sin 930 Degrees

Example 1: Find the value of sin 930° if cosec 930° is 2.
Solution:
Since, sin 930° = 1/csc 930°
⇒ sin 930° = 1/(2) = 0.5 
Example 2: Simplify: 2 (sin 930°/sin 2010°)
Solution:
We know sin 930° = sin 2010°
⇒ 2 sin 930°/sin 2010° = 2(sin 930°/sin 930°)
= 2(1) = 2 
Example 3: Find the value of 2 × (sin 465° cos 465°). [Hint: Use sin 930° = 0.5]
Solution:
Using the sin 2a formula,
