Answer:
2π
Step-by-step explanation:
Given :- 2cos²¢ + 3 sin¢ = 0
= 2(1-sin²¢) + 3sin¢ = 0
= > 2- 2sin²¢ + 3sin¢ = 0
=> 2 sin²¢ -4 sin¢ + sin¢ -2 =0
=> 2sin¢ ( sin¢ -2) + 1( sin¢ -2) = 0
=> (2sin¢ +1)(sin¢ - 2) = 0
°•° sin¢ = 2 never possible . it's range is from -1to 1
sin¢ = -1/2
¢ = - π/6 , -5π/6 , 7π/6 , 11/6
required sum = -π-5π+7π+11π/6 = 12π/6 = 2π Answer
