Question
General Solution of θ which is satisfies the equations sin θ = - 
and tan θ = 
and tan θ = Options
A.nπ + (-1)n π/6
B.nπ + π/6
C.2nπ ± π/6
D.None of these
Solution
sin θ = - 
and tan θ = 
⇒ θ = 
sin θ = sin (π +
)
⇒ θ = 7π/6
sin θ = sin (2π -
)
= sin
⇒ θ = 
General solution θ = 2nπ +
and tan θ = ⇒ θ = sin θ = sin (π +
)⇒ θ = 7π/6
sin θ = sin (2π -
)= sin
⇒ θ = General solution θ = 2nπ +
