Sin 34 Degrees
The value of sin 34 degrees is 0.5591929. . .. Sin 34 degrees in radians is written as sin (34° × π/180°), i.e., sin (17π/90) or sin (0.593411. . .). In this article, we will discuss the methods to find the value of sin 34 degrees with examples.
- Sin 34°: 0.5591929. . .
- Sin (-34 degrees): -0.5591929. . .
- Sin 34° in radians: sin (17π/90) or sin (0.5934119 . . .)
What is the Value of Sin 34 Degrees?
The value of sin 34 degrees in decimal is 0.559192903. . .. Sin 34 degrees can also be expressed using the equivalent of the given angle (34 degrees) in radians (0.59341 . . .).
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 34 degrees = 34° × (π/180°) rad = 17π/90 or 0.5934 . . .
∴ sin 34° = sin(0.5934) = 0.5591929. . .
Explanation:
For sin 34 degrees, the angle 34° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 34° value = 0.5591929. . .
Since the sine function is a periodic function, we can represent sin 34° as, sin 34 degrees = sin(34° + n × 360°), n ∈ Z.
⇒ sin 34° = sin 394° = sin 754°, and so on.
Note: Since, sine is an odd function, the value of sin(-34°) = -sin(34°).
