Answer the following True or False.

Let $\displaystyle {F}{\left({x}\right)}={\int_{{{8}}}^{{{\sin{{\left({2}{x}\right)}}}}}}{f{{\left({x}\right)}}}{\left.{d}{x}\right.}$ , then $\displaystyle {F}'{\left({x}\right)}={2}{\cos{{\left({2}{x}\right)}}}{f{{\left({\sin{{\left({2}{x}\right)}}}\right)}}}$ .
