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.
The given options are 1) y = (cos x) / x is neither and 2) y = (sin x) / x is even.
Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right-angled (not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
1) y = (cos x) / x is neither, since cos x is even and x is 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.
We know that (-) / (-) is positive, just as (+) / (+) is positive.
