## What is the value of tan at 1?

Tan 1 degrees is the value of tangent trigonometric function for an angle equal to 1 degrees. The value of tan 1° is 0.0175 (approx).

**Is tan 180 undefined?**

θ | sin θ | tan θ |
---|---|---|

0° | 0 | 0 |

90° | 1 | undefined |

180° | 0 | 0 |

270° | −1 | undefined |

**Why is tan 90?**

tan90∘ is undefined because you can’t divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined.

### What is the exact value of tan 90?

undefined

The exact value of tan 90 is infinity or undefined.

### What is TANX equal to?

sin x cos x

tan x = sin x cos x .

**Why is tan 270 undefined?**

Explanation: For tan 270 degrees, the angle 270° lies on the negative y-axis. Thus tan 270° value is not defined. Since the tangent function is a periodic function, we can represent tan 270° as, tan 270 degrees = tan(270° + n × 180°), n ∈ Z.

**Where is TANX undefined?**

The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.

#### Is tan always 90?

Why is Tan 90 undefined? As we have got the result as infinity, and we cannot define infinity, therefore tan 90 is undefined.

#### Can you do trig without a calculator?

Evaluating Trigonometric Functions without a Calculator For trigonometric functions of Graphical Axes, you can easily solve the problems using the easy-to-remember patterns for 0°, 90°, 180°, and 270°. The values of Sine and Cosine for these angles are quite easy to be saved in your memory.

**What is tan 2x?**

Hence, the value of tan 2x is -15/8.
