2.12.19 Asymptotic Analysis

Condition: write an asymptotic representation of a function set by an integral. The asymptotic representation should be brought to a member, which is an infinitely small function at \ (\ quad X \ Rightarrow a \). \ [F (x) = \ int_ {x}^{1} \ frac {\ sin t} {t {3} d t, \ quad X \ Rightarrow+0 \]
