Answer to Question #5035 in Trigonometry for maureen

Question

if secx,0and cotx,0,in which quadrant does the terminal side of the angle x lie?

Answer 1

Dear Maureen
the question is not clear. Did you mean secx>0and cotx>0& ? If so then take a look at the solution
we know that sec x=1/cosx>0 hence cos x>0 => it's 1 or 4 quadrant
cot x=sin x/ cos x>0 => sin x>o (because we've already known that cos >0) hence it's 1 quadrant
