If 2 sin2α - 3 = 0 , find the value of α .
Answer & explanation
Correct answer: option 2
2 sin2α - 3 = 0
sin2α = \(\frac{3}{2}\)
sinα = \(\frac{\sqrt {3}}{2}\)
α = 60°
If 2 sin2α - 3 = 0 , find the value of α .
Correct answer: option 2
2 sin2α - 3 = 0
sin2α = \(\frac{3}{2}\)
sinα = \(\frac{\sqrt {3}}{2}\)
α = 60°
