## Why is tan90 infinite?

In this definition the tan of the angle is the opposite side to the angle divided by the adjacent side to the angle. You can’t have a triangle with a second 90° angle so tan (90°) is undefined. Since any angle having 90° will be on the y-axis, x will be zero. Division by zero is undefined therefore so is tan (90°).

## Why is tangent infinite?

Since the tangent of an angle is “Opposite over Adjacent” (TOA), the result of dividing a number by a very small number produces a very large one. Eventually, the side BC approaches zero and the result approaches infinity.

**What is tan infinity?**

Only Tan 45 is equal to 1. When the value of x goes towards 90, the value goes higher and higher as it goes to an infinity value. tan(infinity) is not =1.

### How do you find tan 90 Theta?

tan (90° + θ) = – cot θ.

### Is tan 90 infinity or infinity?

The exact value of tan 90 is infinity or undefined.

**Why is tan 90 and tan 270 undefined?**

At 90 degrees we must say that the tangent is undefined (und), because when you divide the leg opposite by the leg adjacent you cannot divide by zero. At 270 degrees we again have an undefined (und) result because we cannot divide by zero..

## What is the value of 1 infinity?

undefined

Infinity is a concept, not a number; therefore, the expression 1/infinity is actually undefined.

## What is the natural log of infinity?

The answer is ∞ . The natural log function is strictly increasing, therefore it is always growing albeit slowly. The derivative is y’=1x so it is never 0 and always positive.

**What is infinity approach?**

Infinity is a concept, not a number; therefore, the expression 1/infinity is actually undefined. In mathematics, a limit of a function occurs when x gets larger and larger as it approaches infinity, and 1/x gets smaller and smaller as it approaches zero.

### Why is COT 90 defined?

Why is COT 90 defined? The value of cot 90 is defined since the ratio of cos 90 degrees to sin 90 degrees is defined to a finite value. That means, sin 90° = 1, cos 90° = 0 and cot 90° = cos 90°/sin 90° = 0/1 = 0.

### What is Cosec 90 a?

We can use trigonometric identities to represent cosec 90° as, -cosec(180° + 90°) = -cosec 270° sec(90° – 90°) = sec 0° -sec(90° + 90°) = -sec 180°

**Is tan90 a real number?**

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