Functions can be symmetrical about the y-axis, which means that if we reflect their graph about the y-axis we will get the same graph. There are other functions that we can reflect about both the x- and y-axis and get the same graph. These are two types of symmetry we call even and odd functions.

A function with a graph that is symmetric about the origin is called an odd function. Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, [latex]f\left(x\right)={2}^{x}\\[/latex] is neither even nor odd.

All trigonometric functions are periodic. They are useful because one can determine the value of the function anywhere in the domain. If a function is periodic, then there is some value n for which over the entire domain of the function. The smallest n-value that fits the function is called the period of f(x). Trigonometric functions are also ...

Sine is an odd function, and cosine is an even function. You may not have come across these adjectives “odd” and “even” when applied to functions, but it’s important to know them. A function f is said to be an odd function if for any number x, f(–x) = –f(x). A function f is said to be an even function if for any number x, f(–x) = f(x). Most functions are neither odd nor even functions, but some of the most important …

And you want to be very careful here. Not all even or odd functions even have exponents in them. They could be trigonometric functions. They might be some other type of wacky functions. You don't have to have exponents. It's just that these exponents are probably where the motivations for calling these even functions and odd functions came from.

Trigonometric Even-odd Functions | Brilliant Math ...

brilliant.org/wiki/trigonometric-even-odd-functions/

Even and odd functions are functions satisfying certain symmetries: even functions satisfy f (x) = f (− x) f(x)=f(-x) f (x) = f (− x) for all x x x, while odd functions satisfy f (x) = − f (− x) f(x)=-f(-x) f (x) = − f (− x). Trigonometric functions are examples of non-polynomial even (in the case of cosine) and odd (in the case of sine and tangent) functions.
