Question

Use algebra to find all values of x between 0 and 2π that satisfy this equation.

4sin^2x-3=0

Answer 1

4sin²x-3=0
4sin²x=3
sin²x=3/4
sinx=±√3/2

Answer 2

So, 60º is good. (TO prove this, you can draw 30-60-90 and find the sine of 60. IF YOU WANT)

Answer 3

Hm, so in radians the answer would be pi/3 and 5pi/6?

Answer 4

:)

Answer 5

Alright, thank you :D
