Why is the tangent of 90 degrees undefined?
Why is the tangent of 90 degrees 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. In the third quadrant the hypotenuse extended will now meet the tangent line above the x-axis and is now positive again.
Is tan 90 degrees a real number?
Tan 90 degrees is the value of tangent trigonometric function for an angle equal to 90 degrees. The value of tan 90° is undefined(∞).
Where is tan zero?
Common angles again

What degree is tan undefined?
The exact value of tan 90 is infinity or undefined.
At what angles is the value of tangent undefined?
| θ | sin θ | tan θ |
|---|---|---|
| 0° | 0 | 0 |
| 90° | 1 | undefined |
| 180° | 0 | 0 |
| 270° | −1 | undefined |
Is tan 90 undefined?
Is tan 90 undefined or infinity?
As we have got the result as infinity, and we cannot define infinity, therefore tan 90 is undefined.
Where is tan undefined?
The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.
Is tan 90 infinity or undefined?
undefined
tan( 90°) 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.
Where tan is undefined?
Answer and Explanation: The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.
