Question

If sin Φ(as theta) =-1/2 and Φ lies in quadrant IV Find the values of all the other five trigonometric function

Answer 1

sinA=-1/2 so cosA=√1-(-1/2)^2=√3\2 as it is positive in fourth quadrant . tanA=sinA/cosA= (-1/2)/(√3/2) = -1/√3 . cotA=1/tanA=1/(-1/√3)= -√3. cosecA=1/sinA=
1/(1/2) =2. secA=1/(√3/2) =2/√3. Hope it helps you...

Answer 2

Step-by-step explanation:

find the remaining trigonometry function if

sin theta = -1/2 , P(Q) is in 4th quadrant ?
