Question

Solve sin(x) - √(1 - 3sin²(x)) = 0 given that 0° ≤ x ≤ 360°.

Answer 1

\[\sin x - \sqrt{1 - 3 \sin^2 x} = 0\]
\[\sin x =\sqrt{1 - 3 \sin^2 x}\]

does that get the ball rolling?

Answer 2

I did that and then squared both sides

Answer 3

cool. so problem solved? or do you need more?

Answer 4

squaring both side
sin^2 x=1-3 sin^2 x
4 sin^2 x=1
sin x=+1/2 or -1/2
x=30 degree or 210 degree

Answer 5

good job
