4sin2 x – 3 = 0, find x if 0 (geq) x (geq) 90o
-
A.
30o -
B.
45o -
C.
60o -
D.
9o
Correct Answer: Option C
Explanation
4 sin2x – 3 = 0
sin2x = (frac{3}{4})
Sin x = (pm) (sqrt{frac{3}{4}})
= (pm) (sqrt{frac{3}{4}})
= 60o
4 sin2x – 3 = 0
sin2x = (frac{3}{4})
Sin x = (pm) (sqrt{frac{3}{4}})
= (pm) (sqrt{frac{3}{4}})
= 60o
