i think that (cos x)/x is the question................... so that is odd........ because when x is negative the function is negative........

both the negaitives cancel right

no they cannot be negative because cos(-x) is cos x

convince yourself that an even function over an odd function is odd
what about sin(-x)/x
even
draw a right triangle ........and find cos x as base/hypotenuse if you rotate x in the anti clockwise direction so base is still the same...........
hence it is positive............
