Question

1.) Is y= cosx/x an even, odd , or neither 2.) Is y=sinx/x and even, odd , or neither

Answer 1

Answer:

Step-by-step explanation:

1) y = (cos x) / x is neither, since cos x is even and x is odd.  Expressions such as this are neither even nor odd. /

2) y = (sin x) / x is even, since sin x and x would either both be positive at the same time or negative at the same time.  Recall that (-) / (-) is positive, just as (+) / (+) is positive.
