What is tan 180°?
Tangent function is defined as the ratio of the opposite side to the adjacent side of a specific angle of a right-angled triangle.
Answer: The value of tan 180° is 0.
To find the value of tan 180° we will use the trigonometric formula tan θ = sin θ / cos θ
The value of sin 180° = 0
Also, the value of cos 180° = -1
So, tan 180° = sin 180° / cos 180°
= 0 / (-1)
