Thread: find the solutions (0,2π)

I know its alot but can somebody run me through these



find the solutions (0,2π)
7csc^2x=(1-7√3)cotx-√3-7


find the solutions (0,2π)
2csc3x - 4/3 √3=0

find the solutions (0,2π)
3sec^2 x/2-1=0

find the solutions (0,2π)
14 sin^2x(6-7√3)cosx+3√3-14=6


find the solutions (0,2π)
6cot^2x-18=0

find the solutions (0,2π)
tan^2Θ= -3/2 secΘ

find the solutions (0,2π)
2cos^2x=13sinx-5

So, have you tried anything?

yes!!!! they all reduce to quadratic equations . u must use basic trigonometric identies.
