A function is odd function if f (-x) = - f(x). A function is even function if f(-x) = f(x). f(x) = sin (x) and f(x) = x are examples of odd functions and f(x) = cos x and f(x) = e^ (-x)^2 are examples of even functions.
Give two more examples of even functions and two more examples of odd functions.
Show that for odd functions f (x), integral of f(x) from negative infinity to infinity = 0
if such improper integral exists
Show that if f (x) is odd function and f ’(x) (the derivative of f) is defined, then f ’(x) is even function.
