If 4sin2θ = 2 , then find the value of θ.
Answer & explanation
Correct answer: option 4
4sin2θ = 2
sin2θ =\(\frac{1}{2}\) [sin30°=\(\frac{1}{2}\)]
sin2θ = sin30°
2θ = 30°
θ=\(\frac{30°}{2}\)
θ =15°
If 4sin2θ = 2 , then find the value of θ.
Correct answer: option 4
4sin2θ = 2
sin2θ =\(\frac{1}{2}\) [sin30°=\(\frac{1}{2}\)]
sin2θ = sin30°
2θ = 30°
θ=\(\frac{30°}{2}\)
θ =15°
