# Where is the tangent function undefined?

Looking for an answer to the question: Where is the tangent function undefined? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Where is the tangent function undefined?

To plot the parent graph of a tangent function f(x) = tan x where x represents the angle in radians, you start out by finding the vertical asymptotes. Those asymptotes give you some structure from which you can fill in the missing points. Find the vertical asymptotes so you can find the domain.

To find out what a tangent equals, use the equation for a tangent, which is tan(degrees) = opposite / adjacent. This equation will determine what the tangent of an angle equals by using the triangle's opposite angle and adjacent angle from the initial angle used at the beginning of the equation in the tan(degrees) aspect.

Since a tangent is a straight line graph, it has equation y = mx + c, with m gradient and c the y-intercept. We then substitute a point on the graph (the tangent contact point) into this equation to solve for the y-intercept value c, and rewrite in standard form.

## Why is tangent 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.

## Is tan 90 undefined or infinity?

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.

## What trig functions are undefined at 0?

First, the the secant, cosecant, and cotangent functions are the reciprocals of the cosine, sine, and tangent functions, respectively. Second, there is no value for which the cosine and sine functions are undefined. This is because r is the distant from the origin to the point (x,y) ≠ (0,0) on the terminal ray.

## Why is the tan of 90 undefined?

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.

## 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 tangent undefined at PI 2 and?

Because tan(x) is defined as being equal to sin(x)/cos(x), and cos(π/2)=0. So tan(π/2)=1/0, which is undefined because of the division by zero.

## At what angles is tangent undefined?

## How do you know if a trig function is undefined?

When an angle lies along an axis, the values of the trigonometric functions are either 0, 1, -1, or undefined. When the value of a trigonometric function is undefined, it means that the ratio for that given function involved division by zero.

## 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 90 undefined?

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.

### Where is the tangent function undefined?

The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer. Why TAN 90 is infinity? the tangent of 90 degrees is equal to length of opposite side divided by length of adjacent side which would become length of the hypotenuse divided by 0 which is undefined. the infinity measurement expresses the fact that the tangent is undefined at 90 degrees.
