- Tan 37° in decimal: 0.7535540. . .
- Tan (-37 degrees): -0.7535540. . .
- Tan 37° in radians: tan (0.6457718 . . .)
What is the Value of Tan 37 Degrees?
The value of tan 37 degrees in decimal is 0.753554050. . .. Tan 37 degrees can also be expressed using the equivalent of the given angle (37 degrees) in radians (0.64577 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 37 degrees = 37° × (π/180°) rad = 0.6457 . . .
∴ tan 37° = tan(0.6457) = 0.7535540. . .
Explanation:
For tan 37 degrees, the angle 37° lies between 0° and 90° (First Quadrant). Since tangent function is positive in the first quadrant, thus tan 37° value = 0.7535540. . .
Since the tangent function is a periodic function, we can represent tan 37° as, tan 37 degrees = tan(37° + n × 180°), n ∈ Z.
⇒ tan 37° = tan 217° = tan 397°, and so on.
Note: Since, tangent is an odd function, the value of tan(-37°) = -tan(37°).
Methods to Find Value of Tan 37 Degrees
The tangent function is positive in the 1st quadrant. The value of tan 37° is given as 0.75355. . .. We can find the value of tan 37 degrees by:

Tan 37 Degrees Using Unit Circle
To find the value of tan 37 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 37° angle with the positive x-axis.
- The tan of 37 degrees equals the y-coordinate(0.6018) divided by x-coordinate(0.7986) of the point of intersection (0.7986, 0.6018) of unit circle and r.
Hence the value of tan 37° = y/x = 0.7536 (approx).
