### 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

### 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 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 kind of symmetry does an even function have?

A function f(x) is even if f(-x) = f(x). A graph of f(x) would be symmetric about the y-axis (vertical symmetry about x=0). f(x) need not be "well-behaved" or even continuous, unlike the examples given in Wikipedia article on "Even and odd functions". The article does make this clear - under "Some facts". Read More

### Can you have line of symmetry but not rotational symmetry?

Yes. An isosceles triangle, for example, is symmetric about the bisector of its odd angle but has no rotational symmetry. Read More

### What kind of symmetry does a fish have?

Bilateral Symmetry is the symmetry a jellyfish has. 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 kind of symmetry is a man?

Bilateral symmetry. All humans have bilateral symmetry. Read More

### What kind of symmetry does a jellyfish have?

Radial symmetry A jellyfish has radial symmetry. Radial symmetry Read More

### What kind of symmetry does a human have?

None. Even the most symmetrical face is not totally symmetrical. And since the heart, stomach, liver etc are on one side of the body, the internal organs are certainly not symmetrical. Read More

### 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

### Is a sponge a radial symmetry or bilateral symmetry?

Sponges really don't have any kind of symmetry. Read More

### What kind of symmetry does a circle have?

It has rotational symmetry of infinite order as well as an infinite number of axes of symmetry. 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
