Tan 900 Degrees
The value of tan 900 degrees is 0. Tan 900 degrees in radians is written as tan (900° × π/180°), i.e., tan (5π) or tan (15.707963. . .). In this article, we will discuss the methods to find the value of tan 900 degrees with examples.
 Tan 900°: 0
 Tan (900 degrees): 0
 Tan 900° in radians: tan (5π) or tan (15.7079632 . . .)
What is the Value of Tan 900 Degrees?
The value of tan 900 degrees is 0. Tan 900 degrees can also be expressed using the equivalent of the given angle (900 degrees) in radians (15.70796 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 900 degrees = 900° × (π/180°) rad = 5π or 15.7079 . . .
∴ tan 900° = tan(15.7079) = 0
Explanation:
For tan 900°, the angle 900° > 360°. We can represent tan 900° as, tan(900° mod 360°) = tan(180°). The angle 900°, coterminal to angle 180°, lies on the negative xaxis.
Thus, tan 900 degrees value = 0
Similarly, given the periodic property of tan 900°, it can also be written as, tan 900 degrees = (900° + n × 180°), n ∈ Z.
⇒ tan 900° = tan 1080° = tan 1260°, and so on.
Note: Since, tangent is an odd function, the value of tan(900°) = tan(900°) = 0.
Methods to Find Value of Tan 900 Degrees
The value of tan 900° is given as 0. We can find the value of tan 900 degrees by:
 Using Unit Circle
 Using Trigonometric Functions
Tan 900 Degrees Using Unit Circle
To find the value of tan 900 degrees using the unit circle, represent 900° in the form (2 × 360°) + 180° [∵ 900°>360°] ∵ The angle 900° is coterminal to 180° angle and also tangent is a periodic function, tan 900° = tan 180°.
 Rotate ‘r’ anticlockwise to form 180° or 900° angle with the positive xaxis.
 The tan of 900 degrees equals the ycoordinate(0) divided by xcoordinate(1) of the point of intersection (1, 0) of unit circle and r.
Hence the value of tan 900° = y/x = 0
Tan 900° in Terms of Trigonometric Functions
Using trigonometry formulas, we can represent the tan 900 degrees as:
 sin(900°)/cos(900°)
 ± sin 900°/√(1  sin²(900°))
 ± √(1  cos²(900°))/cos 900°
 ± 1/√(cosec²(900°)  1)
 ± √(sec²(900°)  1)
 1/cot 900°
Note: Since 900° lies on the negative xaxis, the final value of tan 900° is 0.
We can use trigonometric identities to represent tan 900° as,
 cot(90°  900°) = cot(810°)
 cot(90° + 900°) = cot 990°
 tan (180°  900°) = tan(720°)

Examples Using Tan 900 Degrees

Example 1: Simplify: 4 (tan 900°/cot(45°))
Solution:
We know tan 900° = 0 and cot(45°) = 1
⇒ 4 (tan 900°/cot(45°)) = 4(0)
= 0 
Example 2: Find the value of tan 900° + tan 45°.
Solution:
Since, tan 900° = 0 and tan 45° = 1
⇒ tan 900° + tan 45° = 0 + 1 = 1 
Example 3: Find the value of tan 900°/(1  tan²(0°)). [Hint: Use tan 900° = 0]
Solution:
∵ tan 900° = tan 0° = 0
tan 900°/(1  tan²(0°)) = 0/(1  0)
= 0
