Trigonometry Classwork 5-23-17

In 1-9, solve each equation for x such that 0\leq x<2\pi.

  1. 2\sin(3x)+1=0
  2. 2\cos(2x)+1=0
  3. \sec(4x)-2=0
  4. \sqrt{3}\tan(3x)+1=0
  5. 2\cos(3x)=1
  6. 2\sin{x}\tan{x}-\tan{x}=1-2\sin{x}
  7. \sec{x}\tan{x}-\cos{x}\cot{x}=\sin{x}
  8. \tan{x}-3\cot{x}=0
  9. \tan(3x)+1=\sec(3x)
  10. Solve for x such that 0\leq x<2\pi and round to the nearest thousandth: \cos{x}=0.4
