Evaluate the Expressions Using Reference Angles $\csc \left( - 840 ^ { \circ } \right)$

Evaluate the expressions using reference angles. $\csc \left( - 840 ^ { \circ } \right)$ $\cot \left( - 840 ^ { \circ } \right)$

A) $\csc \left( - 840 ^ { \circ } \right) = - \frac { 2 \sqrt { 2 } } { 3 }$ $\cot \left( - 840 ^ { \circ } \right) = \frac { \sqrt { 2 } } { 2 }$
B) $\csc \left( - 840 ^ { \circ } \right) = \frac { \sqrt { 3 } } { 3 }$ $\cot \left( - 840 ^ { \circ } \right) = \frac { \sqrt { 3 } } { 3 }$
C) $\csc \left( - 840 ^ { \circ } \right) = - \frac { \sqrt { 2 } } { 2 }$ $\cot \left( - 840 ^ { \circ } \right) = \frac { \sqrt { 2 } } { 3 }$
D) $\csc \left( - 840 ^ { \circ } \right) = - \frac { 1 } { 3 }$ $\cot \left( - 840 ^ { \circ } \right) = \frac { 1 } { 3 }$
E) $\csc \left( - 840 ^ { \circ } \right) = - \frac { 2 \sqrt { 3 } } { 3 }$ $\cot \left( - 840 ^ { \circ } \right) = \frac { \sqrt { 3 } } { 3 }$
