Question

((5/7) , (-2√6)/7)) Find csc t.

Answer 1

assuming those values are (cos t, sin t)
\[\large \csc t =\frac{ 1 }{ \sin t } = \frac{ 1 }{ \frac{ -2 \sqrt 6 }{ 7 } } = \frac{ -7 }{ 2 \sqrt 6 } = \frac{ -7 }{ 2 \sqrt 6 }*\frac{ \sqrt 6 }{ \sqrt 6 }\]

Answer 2

Thank you so much! (: It'll be \[\frac{-7\sqrt{6} }{ 12 }\]
right?

Answer 3

That's right :)
