Which function is undefined at Pi 2?
Explanation: csc π2 = 1,sec π2 = 1/0(undefined) and cot π2 = 0.
For which value of is CSC () undefined?
Trigonometric functions are undefined when they represent fractions with denominators equal to zero. Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to 0. The value of sin (0) is 0, so the cosecant of 0 must be undefined.
What is an undefined function?
A function is undefined when the denominator is equal to zero. If there are variables in the denominator, the point at which the expression in the denominator is zero is the point where that function is undefined.
How do you know if a function is undefined?
How do we know when a numerical expression is undefined? It is when the denominator equals zero. When we have a denominator that equals zero, we end up with division by zero. We can't divide by zero in math, so we end up with an expression that we can't solve.
Where is cosine undefined?
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.
Where is the tangent function undefined?
Answer and Explanation: The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.
How do I know if a function is undefined?
How do we know when a numerical expression is undefined? It is when the denominator equals zero. When we have a denominator that equals zero, we end up with division by zero.
How do you find the undefined function?
0:171:07Learn to find the values the function is undefined, then write domainYouTube
What is an example of an undefined function?
A function is said to be "undefined" at points outside of its domain – for example, the real-valued function. is undefined for negative. (i.e., it assigns no value to negative arguments). In algebra, some arithmetic operations may not assign a meaning to certain values of its operands (e.g., division by zero).
Is 0 over something undefined?
We know that 0 divided by any number is 0, but we also know that any number divided by 0 is undefined.
What angle is sin undefined?
| θ | sin θ | tan θ |
|---|---|---|
| 90° | 1 | undefined |
| 180° | 0 | 0 |
| 270° | −1 | undefined |
| 360° | 0 | 0 |
Which tan values are undefined?
Answer and Explanation: The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.
Is tan 180 undefined?
Tan 180 degrees is the value of tangent trigonometric function for an angle equal to 180 degrees. The value of tan 180° is 0.
Is undefined equal to zero?
We can say that zero over zero equals "undefined." And of course, last but not least, that we're a lot of times faced with, is 1 divided by zero, which is still undefined.
When a function is not defined?
A function is not defined or is undefined if the value to be inputted is not in its domain.
How do you know function is undefined?
A function is undefined when the denominator is equal to zero. If there are variables in the denominator, the point at which the expression in the denominator is zero is the point where that function is undefined.
How do you find an undefined function?

How do you know when a function is undefined?
A rational expression is undefined when the denominator is equal to zero. To find the values that make a rational expression undefined, set the denominator equal to zero and solve the resulting equation.
What value is undefined?
How do we know when a numerical expression is undefined? It is when the denominator equals zero. When we have a denominator that equals zero, we end up with division by zero. We can't divide by zero in math, so we end up with an expression that we can't solve.
Where is tan θ undefined?
Well, tangent theta is undefined when cosine theta equals zero.
Which trig functions can return with undefined?
There are two important points to notice as you study these definitions. 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.
Where is a tangent function undefined?
Answer and Explanation: The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.
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 tan undefined?
The tangent function, tan(x) is undefined when x = (π/2) + πk, where k is any integer.
For what values will the function be undefined?
A function is said to be "undefined" at points outside of its domain – for example, the real-valued function. is undefined for negative. (i.e., it assigns no value to negative arguments). In algebra, some arithmetic operations may not assign a meaning to certain values of its operands (e.g., division by zero).
How do you tell if a function is defined?
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.
What is a undefined function?
A function is undefined when the denominator is equal to zero. If there are variables in the denominator, the point at which the expression in the denominator is zero is the point where that function is undefined.
Which way is undefined?
A line has a slope that is considered undefined when it does not have any horizontal run. It will be a straight vertical line.
What degree is tan undefined?
90 degrees 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.
Can Cos be undefined?
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.
