Question 814718
you are given cot theta = -1/2 and sin theta >0. Find other functions and give exact answer.
***
Reference angle in quadrant II where cos<0 and sin>0
cotx=cosx/sinx=-1/2
hypotenuse of reference right triangle=&#8730;(-1)^2+2^2)=&#8730;(1+4)=&#8730;5
..
tan theta=-2
sin theta=2/&#8730;5=2&#8730;5/5
cos theta=-1/&#8730;5=-&#8730;5/5
csc theta=&#8730;5/2
sec theta=-&#8730;5
