The Answer of By graphing the function $$f ( x ) = \frac { ( \cos x - \cos 5 x ) } { x ^ { 2 } }$$
and zooming in toward the point where the graph crosses the $y$-axis, estimate the value of $\lim _ { x \rightarrow 0 } f ( x )$.

By Graphing the Function f(x)=(cos⁡x−cos⁡5x)x2f ( x ) = \frac { ( \cos x - \cos 5 x ) } { x ^ { 2 } }f(x)=x2(cosx−cos5x)​

By Graphing the Function $f ( x ) = \frac { ( \cos x - \cos 5 x ) } { x ^ { 2 } }$
