Tan 50 Degrees
The value of tan 50 degrees is 1.1917535. . .. Tan 50 degrees in radians is written as tan (50° × π/180°), i.e., tan (5π/18) or tan (0.872664. . .). In this article, we will discuss the methods to find the value of tan 50 degrees with examples.
- Tan 50° in decimal: 1.1917535. . .
- Tan (-50 degrees): -1.1917535. . .
- Tan 50° in radians: tan (5π/18) or tan (0.8726646 . . .)
What is the Value of Tan 50 Degrees?
The value of tan 50 degrees in decimal is 1.191753592. . .. Tan 50 degrees can also be expressed using the equivalent of the given angle (50 degrees) in radians (0.87266 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 50 degrees = 50° × (π/180°) rad = 5π/18 or 0.8726 . . .
∴ tan 50° = tan(0.8726) = 1.1917535. . .
Explanation:
For tan 50 degrees, the angle 50° lies between 0° and 90° (First Quadrant). Since tangent function is positive in the first quadrant, thus tan 50° value = 1.1917535. . .
Since the tangent function is a periodic function, we can represent tan 50° as, tan 50 degrees = tan(50° + n × 180°), n ∈ Z.
⇒ tan 50° = tan 230° = tan 410°, and so on.
Note: Since, tangent is an odd function, the value of tan(-50°) = -tan(50°).
Methods to Find Value of Tan 50 Degrees
The tangent function is positive in the 1st quadrant. The value of tan 50° is given as 1.19175. . .. We can find the value of tan 50 degrees by:
- Using Unit Circle
- Using Trigonometric Functions
Tan 50 Degrees Using Unit Circle
To find the value of tan 50 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 50° angle with the positive x-axis.
- The tan of 50 degrees equals the y-coordinate(0.766) divided by x-coordinate(0.6428) of the point of intersection (0.6428, 0.766) of unit circle and r.
Hence the value of tan 50° = y/x = 1.1918 (approx).
Tan 50° in Terms of Trigonometric Functions
Using trigonometry formulas, we can represent the tan 50 degrees as:
- sin(50°)/cos(50°)
