Domain:[0,2π)
1.(square root 2)/2 co-secant x − 1 = 0
x=π/4, 3π/4
..
2.16 cosine^2 x − 4 = 0
cos(x)=±(1/2)
x=π/3, 2π/3, 4π/3, 5π/3
..
3. 4 cosine^3 x = 4 cosine x
cos^3(x)-cos(x)=0
cos(x)(cos^2(x)-1)=0
cos(x)=0
x=π/2, 3π/2
cos^2(x)-1=0
cos(x)=±1
x=0, π
..
5. 2 cosine 3x − 1 = 0
cos(3x)=1/2
3x=π/3, 5π/3
x=π/9, 5π/9
