By Graphing the Function $f(x)=\frac{(\cos x-\cos 6 x)}{x^{2}}$ And Zooming in Toward the Point Where the Graph Crosses

question 29

Short Answer

By graphing the function $f(x)=\frac{(\cos x-\cos 6 x)}{x^{2}}$ and zooming in toward the point where the graph crosses the y-axis, estimate the value of $\lim _{x \rightarrow 0} f(x)$
