Even and Odd Functions https://www.youtube.com/watch?v=oKKcIK_PgEk(1) Even function: If we put (–x) in place of x in the given function and if f(–x) = f(x), ∀ x ∈ domain then function f(x) is called even function. e.g. f(x) = ex + e-x , f(x) = x2, f(x) = x sin x, f(x) = cos x, f(x) = x2 cos x all are even functions.Examples: f(x) = x2 + 1f(x) = cos … [Read more...] about Even and Odd Functions
