$\csc\theta=-2\,and\, \cot\theta>0$

my solution

$x=-2$

$y=-1$

$r=\sqrt{5}$

$\displaystyle \sin\theta=-\frac{1}{\sqrt{5}}$

$\displaystyle\cos\theta=-\frac{2}{\sqrt{5}}$

$\displaystyle\cot\theta=2$

$\displaystyle\tan\theta=\frac{1}{2}$

$\displaystyle\sec\theta=-\frac{\sqrt{5}}{2}$

are they correct?
