Wednesday 3 May class (delayed post)

Posted on May 2, 2017 by Sybil Shaver

This post is delayed while I get some files in order for you. In the meantime, review what we worked on in class, and you cans start the WeBWorK (only 2 problems!) and this:

Find all exact solutions in [0, 2\pi) for each equation, using the unit circle:

  1. \cos(x) =\frac{\sqrt{3}}{2}
  2. 2\sin(x) = -1 [Hint: first isolate the \sin(x) to get a basic trig equation.]
  3. 2\cos(x) = -\sqrt{2}
  4. \tan(x) = -1
  5. 2\cos(x) + \sqrt{3} = 0
  6. 2\sin(x) -1 = 0
  7. \tan(x) = 0
