Extend the definition of the following by continuity `f(x)=(1-cos7(x-pi))/(5(x-pi)^2)` at the point `x=pi` .

Explanation

`f(x)=frac{1-cos 7(x-pi)}{5(x-pi)^{2}}`



`If `{f}({x})` is continuous at `{x}=pi`, then`



`lim _{x -> pi} f(x)=f(pi)`


`Rightarrow f(pi)=lim _{x -> pi} frac{1-cos 7(x-pi)}{5(x-pi)^{2}}`
