# 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 is cos0 value?

### What fraction is cos 270?

Trigonometric Function Values of Special Angles

θ° | θ^{radians} | cos(θ) |
---|

270° | **3π/2** | 0 |

300° | 5π/3 | 1/2 |

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

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

### What is the exact value of cos315?

### 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 = **cos**^{2}A - sin^{2}A. tan 2A = (2 tan A) / (1 - tan^{2}A)

### 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,**

- -cos(180° - 270°) = -cos(-90°)
- -cos(180° + 270°) = -cos 450°
- sin(90° + 270°) = sin 360°
- sin(90° - 270°) = sin(-180°)
