Tan 750 Degrees
The value of tan 750 degrees is 0.5773502. . .. Tan 750 degrees in radians is written as tan (750° × π/180°), i.e., tan (25π/6) or tan (13.089969. . .). In this article, we will discuss the methods to find the value of tan 750 degrees with examples.
- Tan 750°: 1/√3
- Tan 750° in decimal: 0.5773502. . .
- Tan (-750 degrees): -0.5773502. . . or -1/√3
- Tan 750° in radians: tan (25π/6) or tan (13.0899693 . . .)
What is the Value of Tan 750 Degrees?
The value of tan 750 degrees in decimal is 0.577350269. . .. Tan 750 degrees can also be expressed using the equivalent of the given angle (750 degrees) in radians (13.08996 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 750 degrees = 750° × (π/180°) rad = 25π/6 or 13.0899 . . .
∴ tan 750° = tan(13.0899) = 1/√3 or 0.5773502. . .
Explanation:
For tan 750°, the angle 750° > 360°. We can represent tan 750° as, tan(750° mod 360°) = tan(30°). The angle 750°, coterminal to angle 30°, is located in the First Quadrant(Quadrant I).
Since tangent function is positive in the 1st quadrant, thus tan 750 degrees value = 1/√3 or 0.5773502. . .
Similarly, given the periodic property of tan 750°, it can also be written as, tan 750 degrees = (750° + n × 180°), n ∈ Z.
⇒ tan 750° = tan 930° = tan 1110°, and so on.
Note: Since, tangent is an odd function, the value of tan(-750°) = -tan(750°).

- -cot(90° + 750°) = -cot 840°
- -tan (180° - 750°) = -tan(-570°)
Tan 750 Degrees Using Unit Circle
To find the value of tan 750 degrees using the unit circle, represent 750° in the form (2 × 360°) + 30° [∵ 750°>360°] ∵ The angle 750° is coterminal to 30° angle and also tangent is a periodic function, tan 750° = tan 30°.
- Rotate ‘r’ anticlockwise to form 30° or 750° angle with the positive x-axis.
- The tan of 750 degrees equals the y-coordinate(0.5) divided by x-coordinate(0.866) of the point of intersection (0.866, 0.5) of unit circle and r.
Hence the value of tan 750° = y/x = 0.5774 (approx).
