What are odd and even functions?
There are two main types of functions:
- odd functions: if the input of these functions is negative, the result will be negative; if the input is positive (with the same absolute value of the negative input) the output will be positive:
Examples of odd functions are sin(x), x³, -x, x etc… .
- even functions: regardless of the sign of the input, the result will always be positive:
Examples are x², |x|, 1-x², cos(x) etc… .
And this is what you need to know about odd and even functions! If you have any questions, leave a comment and I will be happy to reply!
