Trigonometric EquationHard
Question
The maximum value of sin 
+ cos 
is attained at θ ∈ (0, π/2)
+ cos is attained at θ ∈ (0, π/2)Options
A.
B.
C.
D.
Solution
Maximum value of sin(θ + π/6) + cos (θ + π/6)
attains at angle = π/4.
So, θ +
⇒ θ = 
attains at angle = π/4.
So, θ +
⇒ θ = Create a free account to view solution
