Find horizontal asymptotes of f(x)=sin^2(x)/x?

Could someone explain how to find the horizontal asymptotes of this problem? Sine squared x over x

    I think that a horizontal asymptote of a curve requires that x->∞.

    So we require limit x->∞ of sin²(x)/x and this =0 since |sin²(x)| ≤1.

    Some define an asymptote to be tangential to a curve at infinity.

    The horizontal asymptote of this function is its value as it approaches infinity. The envelope of sin² is [0,1]. Thus the limit as x → ∞ is 0.
