Tan 46 Degrees
The value of tan 46 degrees is 1.0355303. . .. Tan 46 degrees in radians is written as tan (46° × π/180°), i.e., tan (23π/90) or tan (0.802851. . .). In this article, we will discuss the methods to find the value of tan 46 degrees with examples.
- Tan 46° in decimal: 1.0355303. . .
- Tan (-46 degrees): -1.0355303. . .
- Tan 46° in radians: tan (23π/90) or tan (0.8028514 . . .)
What is the Value of Tan 46 Degrees?
The value of tan 46 degrees in decimal is 1.035530313. . .. Tan 46 degrees can also be expressed using the equivalent of the given angle (46 degrees) in radians (0.80285 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 46 degrees = 46° × (π/180°) rad = 23π/90 or 0.8028 . . .
∴ tan 46° = tan(0.8028) = 1.0355303. . .
Explanation:
For tan 46 degrees, the angle 46° lies between 0° and 90° (First Quadrant). Since tangent function is positive in the first quadrant, thus tan 46° value = 1.0355303. . .
Since the tangent function is a periodic function, we can represent tan 46° as, tan 46 degrees = tan(46° + n × 180°), n ∈ Z.
⇒ tan 46° = tan 226° = tan 406°, and so on.
Note: Since, tangent is an odd function, the value of tan(-46°) = -tan(46°).
Methods to Find Value of Tan 46 Degrees
The tangent function is positive in the 1st quadrant. The value of tan 46° is given as 1.03553. . .. We can find the value of tan 46 degrees by:

Tan 46 Degrees Using Unit Circle
To find the value of tan 46 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 46° angle with the positive x-axis.
- The tan of 46 degrees equals the y-coordinate(0.7193) divided by x-coordinate(0.6947) of the point of intersection (0.6947, 0.7193) of unit circle and r.
Hence the value of tan 46° = y/x = 1.0355 (approx).
Tan 46° in Terms of Trigonometric Functions
