Which of the following quantities is negative?

$\begin{array}{l}\mathrm{Cos}\left({\mathrm{Tan}}^{-1}(\mathrm{Tan}4)\right)=\mathrm{Cos}\left({\mathrm{Tan}}^{-1}(\mathrm{Tan}(4-\mathrm{\pi }\left)\right)=\mathrm{Cos}(\mathrm{\pi }-4)=-\mathrm{Cos}4>0\right.\\ \mathrm{Sin}\left({\mathrm{Cot}}^{-1}(\mathrm{Cot}(4-\mathrm{\pi }\left)\right)=\mathrm{Sin}(4-\mathrm{\pi })=-\mathrm{Sin}4>0\right.\\ \mathrm{Tan}\left({\mathrm{Cos}}^{-1}(\mathrm{Cot}(4-\mathrm{\pi }\left)\right)=\mathrm{Tan}(2\mathrm{\pi }-5)=-\mathrm{Tan}5>0\right.\\ \mathrm{Cot}\left({\mathrm{Sin}}^{-1}(\mathrm{Sin}(\mathrm{\pi }-4\left)\right)=\mathrm{Cot}(\mathrm{\pi }-4)=-\mathrm{Cot}4<0\right.\end{array}$
