Question

Use trigonometric identities to write $$\csc x$$ in terms of $$\cos x$$

Choose the correct expression equal to csc $$x$$

A. $$\csc x = \frac { \pm \sqrt { 1 - \cos ^ { 2 } x } } { \cos ^ { 2 } x }$$

B. $$\csc x = \frac { \pm \sqrt { 1 - \cos ^ { 2 } x } } { 1 + \cos ^ { 2 } x }$$

D. $$\csc x = \pm \sqrt { 1 - \cos ^ { 2 } x }$$

D. $$\csc x = \frac { \pm \sqrt { 1 - \cos ^ { 2 } x } } { 1 - \cos ^ { 2 } x }$$
