Answer:
Undefined
Step-by-step explanation:
For a unit circle, which has a radius as 1, we can derive the tangent values of all the degrees. With the help of a unit circle drawn on the XY plane, we can find out all the trigonometric ratios and values.
Answer:
C)Undefined
Not defined
Step-by-step explanation:
According to research ,
Tangent function denotes that for a given right-angled triangle, the tan of angleθ is equal to the ratio of the opposite side to the angle and adjacent side or base.
Tan θ = Opposite Side/Adjacent Side
We can also represent the tangent function as the ratio of the sine function and cosine function.
∴ Tan θ =Sin θ /Cos θ
So, tan 90 degrees in terms of ratio is,
Tan 90°=Sin 900 / Cos90°
From the trigonometric table, we know,
Sin 90° = 1
And,
Cos90° = 0
∴ Tan 90°= 1/0 = Undefined
That means, we cannot define Tan 900 value.
