The Answer of Point P is on the terminal side of θ . Evaluate the six trigonometric functions for θ. If the function is undefined, write "undefined."
-$\mathrm { P } ( \sqrt { 17 } , - \sqrt { 6 } ) ;$ find $\sec \theta$
A) $ -\frac{\sqrt{138}}{23} $
B) $ \frac{\sqrt{391}}{23} $
C) $ -\frac{\sqrt{138}}{6} $
D) $ \frac{\sqrt{391}}{17} $

Point P Is on the Terminal Side of θ P(17,−6);\mathrm { P } ( \sqrt { 17 } , - \sqrt { 6 } ) ;P(17​,−6​);

Point P Is on the Terminal Side of θ $\mathrm { P } ( \sqrt { 17 } , - \sqrt { 6 } ) ;$
