## Is tangent ever undefined?

Since, tan(x)sin(x)cos(x) the **tangent function is undefined when cos(x)0 . Therefore, the tangent function has a vertical asymptote whenever cos(x)0 . Similarly, the tangent and sine functions each have zeros at integer multiples of u03c0 because tan(x)0 when sin(x)0 .**

## Is tan undefined anywhere?

The function **y tan(x) is undefined at all points where cos(x) 0. This is because the tangent of an angle is defined as the sine of that angle divided by the cosine of that angle. In other words, tan(x) sin(x)/cos(x).**

## Is tan undefined at 0?

**tan(u03b8) will be undefined when x 0, since you would be dividing by zero. This places you at an angle of either 90xba or 270xba. Since we are told sin(u03b8) x26lt; 0 (which is to say, the y coordinate is negative), we must be at 270xba. Hope the above helps.**

## What degree is tan undefined?

The exact value of **tan 90 is infinity or undefined.**

## Is tangent undefined at?

The tangent function, tan(x) is undefined when **x (u03c0/2) + u03c0k, where k is any integer.**

## Why is tan of undefined?

The function **y tan(x) is undefined at all points where cos(x) 0. This is because the tangent of an angle is defined as the sine of that angle divided by the cosine of that angle. In other words, tan(x) sin(x)/cos(x).**

## Is tan undefined at 90 degrees?

Tan(t)sin(t)/cos(t), so **if cos(t)0, one is forced to divide by 0 to get tan(t), so tan(t) is undefined. 90 degrees is one angle where cos(90)0. Originally Answered: Can you explain when tan90 is undefined? Tan 90 is always undefined.**

## Can Tangent be undefined?

The trigonometric ratios can also be considered as functions of a variable which is the measure of an angle. Since, tan(x)sin(x)cos(x) **the tangent function is undefined when cos(x)0 . Therefore, the tangent function has a vertical asymptote whenever cos(x)0 .**

## Why is tan sometimes undefined?

At zero degrees this tangent length will be zero. Hence, tan(0)0. As our first quadrant angle increases, the tangent will increase very rapidly. 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**

## Can tan ever be 0?

It is known that the ratio of sine and cosine of the same angle gives the tangent of the same angle. So, if we have the value of sin 0xb0 degree and cos 0xb0 degree, then the value of tan 0xb0 degrees can be calculated very easily. Therefore, the **Tan 0 is equal to 0/1 or 0. It implies that Tan 0 is equal to 0.**

## Is tan 0 defined?

In trigonometry, the value of **tan 0 is 0. The word ‘Trigonometry’ is derived from the Greek word and the subject is developed to solve geometric problems involving triangles. It is used to measure the sides of a triangle.**

## Is tan ever undefined?

The tangent function, tan(x) is **undefined when x (u03c0/2) + u03c0k, where k is any integer.**

## Is tan ever zero?

Similarly, the tangent and sine functions each have zeros at integer multiples of u03c0 because **tan(x)0 when sin(x)0 .**

## What is the value of tan at 0?

Tan 0 degrees is the value of tangent trigonometric function for an angle equal to 0 degrees. The value of tan 0xb0 **is 0**

## For what angles is tan undefined?

## Where is tangent undefined?

Since, tan(x)sin(x)cos(x) the tangent function is undefined **when cos(x)0 . Therefore, the tangent function has a vertical asymptote whenever cos(x)0 . Similarly, the tangent and sine functions each have zeros at integer multiples of u03c0 because tan(x)0 when sin(x)0 .**

## Is tan 0 degrees undefined?

Trigonometric functions are equal to 0, 1, -1 or undefined when the angle lies on an axis, meaning that the angle is equal to 0, 90, 180 or 270 degrees (0, (pi)/2, pi or 3(pi)/2 in radians.) **The value of tan (0) is 0, so the cotangent of (0) must be undefined.**

## Where is the tangent undefined?

Since, tan(x)sin(x)cos(x) the tangent function is undefined **when cos(x)0 . Therefore, the tangent function has a vertical asymptote whenever cos(x)0 . Similarly, the tangent and sine functions each have zeros at integer multiples of u03c0 because tan(x)0 when sin(x)0 .**

## Is tangent undefined at 0?

The function **y tan(x) is undefined at all points where cos(x) 0. This is because the tangent of an angle is defined as the sine of that angle divided by the cosine of that angle. In other words, tan(x) sin(x)/cos(x).**

## What degree is tangent undefined?

**tan(u03b8) will be undefined when x 0, since you would be dividing by zero. This places you at an angle of either 90xba or 270xba. Since we are told sin(u03b8) x26lt; 0 (which is to say, the y coordinate is negative), we must be at 270xba. Hope the above helps.**

## Why the value of tan 90 is undefined?

## Is tan 90 infinity or undefined?

tan( 90xb0) **is undefined. It doesn’t equal undefined. One of the definitions of the tangent function is by using a right triangle where the angle that you are taking the tangent of is not the right angle. In this definition the tan of the angle is the opposite side to the angle divided by the adjacent side to the angle.**

## Is the tangent function undefined?

Answer and Explanation: The tangent function, tan(x) is **undefined when x (u03c0/2) + u03c0k, where k is any integer.**
