Afunction f(x) is even if f(−x) = f(x). which of sine or cosine is even? explain how you know. (b) a function f(x) is odd if f(−x) = −f(x). which of sine or cosine is odd? explain how you know. (c) cosine is a shift of sine. that is, cos(x) = sin(x + c) for some value of c. (actually this is true for many many values of c.) find such a value of c and explain how you know that you are correct.
