Question 806712
Find all five other trigonometric ratios if sinx=-3/7 and tanx>0
***
Reference angle x is in quadrant II where sin<0, cos<0, tan>0
cosx=-&#8730;(1-sin^2x)=-&#8730;(1-9/49)=-&#8730;(40/49)=-&#8730;40/7
sinx=-3/7
cosx=-&#8730;40/7
tanx=sinx/cosx=3/&#8730;40=(3&#8730;40)/40
cscx=-7/3
secx=-7/&#8730;40=-(7&#8730;40)/40
cotx=&#8730;40/3
