# Why Is Tan 270 Undefined?

At 270 degrees we again have an undefined (und) result because we cannot divide by zero..

### How do you find the sin 270 theta?

To find the tangent, we must remember that tanθ=sinθcosθ . In case the value of tangent is undefined, verify using the graph of y=tanθ at θ=270∘ to check whether it is +∞ or −∞ . We know the trigonometric identity sin(270∘+θ)=−cosθ. Hence, the sine of 270 degrees is -1.

### What fraction is cos 270?

Trigonometric Function Values of Special Angles

270°3π/20
300°5π/31/2
315°7π/4√2/2
330°11π/6√3/2

### IS 270 in the third quadrant?

Angles between 180∘ and 270∘ are in the third quadrant. Angles between 270∘ and 360∘ are in the fourth quadrant.

### What is tan 2A?

⇒ tan 2A = 2tanA1−tan2A. Note: (i) In the above formula we should note that the angle on the R.H.S. is half of the angle on L.H.S.

### What quadrant does 270 theta lie?

From the above picture, it is very clear that the angle 270 degree plus theta falls in the fourth quadrant.

### What is csc90?

The exact value of csc(90°) csc ( 90 ° ) is 1 .

### Why is sin 270 theta cos theta?

So , when you subtract it from 270 the new angle is in 3rd quadrant. We know that sin value of any angle in 3rd quadrant is negative. And when you add or subtract theta from 90° or from 270° sin converts to cos . So sin(270° - x) = - cos(x).

### What is sin 270 minus theta?

Therefore, sin (270° - θ) = - cos θ, cos (270° - θ) = cos

### Why is tan 270 undefined?

At 270 degrees we again have an undefined (und) result because we cannot divide by zero..

### What is the value of tan 270 minus theta?

trigonometric ratios of 270 degrees minus theta|sin(270−Θ)=−cosΘ

### What is the formula of cos2a?

cos 2A = cos2A - sin2A. tan 2A = (2 tan A) / (1 - tan2A)

### What are the sine and cosine of − 270?

sin(270o)=−1,cos(270o)=0,tan(270o)=−10= undefined.

### How do you find the value of cos 270?

The value of cos 270 degrees is 0.

We can use trigonometric identities to represent cos 270° as,

1. -cos(180° - 270°) = -cos(-90°)
2. -cos(180° + 270°) = -cos 450°
3. sin(90° + 270°) = sin 360°
4. sin(90° - 270°) = sin(-180°)

### What is the exact value of tan 270?
