### Why is the secant function is an even function and the tangent and cosecant are odd functions?

I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also… Read More

### Does csc -120 equal -csc 120?

Yes. Cosecant is an odd function, that is f(x) = -f(-x). Read More

There is no minimum value for the cosecant function. Read More

### The vertical of the function cosecant are determined by the points that are not in the domain?

The answer depends on what you mean by "vertical of the function cosecant". cosec(90) = 1/sin(90) = 1/1 = 1, which is on the graph. Read More

### Why will sin and cosecant have the same sign?

The cosecant is the reciprocal of the sine function. Now, the reciprocal of a positive number is positive, and the reciprocal of a negative number is negative. Read More

### What is the six trigo function of acute angle?

Sine, Cosine, Tangent, Cosecant, Secant, Cotangent. Read More

### Is the inverse function of secant is the cosecant function?

No. The inverse of the secant is called the arc-secant. The relation between the secant and the cosecant is similar to the relation between the sine and the cosine - they are somehow related, but they are not inverse functions. The secant is the reciprocal of the cosine (sec x = 1 / cos x). The cosecant is the reciprocal of the sine (cos x = 1 / sin x). Read More

### Is the sine functions an odd function?

Yes. Along with the tangent function, sine is an odd function. Cosine, however, is an even function. Read More

### What are even and odd functions?

An even function is a function that creates symmetry across the y-axis. An odd function is a function that creates origin symmetry. Read More

### What is the domain of cosecant of x?

For most purposes the cosecant can be thought of as a function that assumes values over the entire real line. However, it is actually defined over the entire complex plane. Excepting, of course, points where the sine is zero. Read More

### What is the inverse sine function?

The inverse sine is the cosecant, otherwise known as "hypotenuse over opposite" or arcsine. The cosecant is often confused as being the inverse of the cosine, which, in reality, is the secant, otherwise known as "hypotenuse over adjacent" or arccosine. Read More

### What is the difference of odd and even functions?

An even function is symmetric about the y-axis. An odd function is anti-symmetric. Read More

### If the value of a sine function is 0 then the co-secant function is undefined?

That's right. cosecant(x) = 1 / sine(x), so you would get a division by zero. Read More

### How do you find cosecant?

The answer depends on what information you do have. For instance, if you have the sine, the cosecant is simply 1 over the sine. Formally, the cosecant is hypotenuse over opposite. Read More

### Is signam function even or odd and why?

I have no idea about the signam function. The signum function is odd because sgn(-x) = -sgn(x). Read More

### How do you determine if a function is even or odd?

You can tell if a function is even or odd by looking at its graph. If a function has rotational symmetry about the origin (meaning it can be rotated 180 degrees about the origin and remain the same function) it is an odd function. f(-x)=-f(x) An example of an odd function is the parent sine function: y=sinx If a function has symmetry about the y-axis (meaning it can be reflected across the y-axis to produce… Read More

### What is the composition of an even and an odd function?

For an even function, f(-x) = f(x) for all x. For an odd function, f(-x) = -f(x) for all x. Read More

### Is f of x equal to negative x an even or odd function?

It is an odd function. Even functions use the y-axis like a mirror, and odd functions have half-circle rotational symmetry. Read More

### How do you tell if a function is even or odd?

You can tell if a function is even or odd by looking at its graph. If a function has rotational symmetry about the origin (meaning it can be rotated 180 degrees about the origin and remain the same function) it is an odd function. f(-x)=-f(x) An example of an odd function is the parent sine function: y=sinx If a function has symmetry about the y-axis (meaning it can be reflected across the y-axis to produce… Read More

### Can a function be both even and odd?

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. A function can be either. Read More

### How can you determine whether a function is even odd or neither?

Looking at the graph of the function can give you a good idea. However, to actually prove that it is even or odd may be more complicated. Using the definition of "even" and "odd", for an even function, you have to prove that f(x) = f(-x) for all values of "x"; and for an odd function, you have to prove that f(x) = -f(-x) for all values of "x". Read More

### Why you use even and odd function in mathematics?

If you know that a function is even (or odd), it may simplify the analysis of the function, for several purposes. One example is the calculation of definite integrals: for an odd function, the integral of a function from (-x) to (x) (note 1) is zero; for an even function, this integral is twice the integral of the function from (0) to (x). Note 1: That is, the area under the function; for negative values… Read More
