Fill in the first two boxes using the coterminal angle theorem. Then simplify exactly. 

(a) tan(1140)=tan(\displaystyle {\tan{{\left({1140}^{\circ}\right)}}}={\tan{{(}}}+360(\displaystyle +{360}^{\circ}{(}))=\displaystyle {)}{)}=  

(b) cos(2190)=cos(\displaystyle {\cos{{\left({2190}^{\circ}\right)}}}={\cos{{(}}}+360(\displaystyle +{360}^{\circ}{(}))=\displaystyle {)}{)}=  

(c) sin(315)=sin(\displaystyle {\sin{{\left(-{315}^{\circ}\right)}}}={\sin{{(}}}+360(\displaystyle +{360}^{\circ}{(}))=\displaystyle {)}{)}=
