Sin 510 Degrees
The value of sin 510 degrees is 0.5. Sin 510 degrees in radians is written as sin (510° × π/180°), i.e., sin (17π/6) or sin (8.901179. . .). In this article, we will discuss the methods to find the value of sin 510 degrees with examples.
- Sin 510°: 0.5
- Sin 510° in fraction: 1/2
- Sin (-510 degrees): -0.5
- Sin 510° in radians: sin (17π/6) or sin (8.9011791 . . .)
What is the Value of Sin 510 Degrees?
The value of sin 510 degrees in decimal is 0.5. Sin 510 degrees can also be expressed using the equivalent of the given angle (510 degrees) in radians (8.90117 . . .).
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 510 degrees = 510° × (π/180°) rad = 17π/6 or 8.9011 . . .
∴ sin 510° = sin(8.9011) = 1/2 or 0.5
Explanation:
For sin 510°, the angle 510° > 360°. Given the periodic property of the sine function, we can represent it as sin(510° mod 360°) = sin(150°). The angle 510°, coterminal to angle 150°, is located in the Second Quadrant(Quadrant II).
Since sine function is positive in the 2nd quadrant, thus sin 510 degrees value = 1/2 or 0.5
Similarly, sin 510° can also be written as, sin 510 degrees = (510° + n × 360°), n ∈ Z.
⇒ sin 510° = sin 870° = sin 1230°, and so on.
Note: Since, sine is an odd function, the value of sin(-510°) = -sin(510°).
Methods to Find Value of Sin 510 Degrees
The sine function is positive in the 2nd quadrant. The value of sin 510° is given as 0.5. We can find the value of sin 510 degrees by:
- Using Unit Circle
- Using Trigonometric Functions
Sin 510 Degrees Using Unit Circle
To find the value of sin 510 degrees using the unit circle, represent 510° in the form (1 × 360°) + 150° [∵ 510°>360°] ∵ sine is a periodic function, sin 510° = sin 150°.
- Rotate ‘r’ anticlockwise to form a 150° or 510° angle with the positive x-axis.
- The sin of 510 degrees equals the y-coordinate(0.5) of the point of intersection (-0.866, 0.5) of unit circle and r.
Hence the value of sin 510° = y = 0.5

Using trigonometry formulas, we can represent the sin 510 degrees as:
- ± √(1-cos²(510°))
- ± tan 510°/√(1 + tan²(510°))
- ± 1/√(1 + cot²(510°))
- ± √(sec²(510°) - 1)/sec 510°
