HW over the weekend!

The homework over the weekend is to finish up that worksheet that I handed out at the end of class (a pdf version is available under the PDF Textbook and Assignments link section of the main page)

I would strongly suggest to use a bit of time this weekend studying for the incoming test on Tuesday, topics covered include:
  • Determining Quadrants given constraints
    • sin (theta) > 0
    • cos (theta) < 0
  • Evaluating Trig Ratios/Functions... (these are the same thing)
    • KNOW YOUR SPECIAL TRIANGLES!!!
    • Given a coordinate point
      • (3, -4)
      • plot the point (connect the radius from (0,0)[the origin] to the point, create triangle from there)
    • Given a trig ratio
      • sin(theta) = 1/2
        • tan(theta)>0
      • draw reference triangle (use the ratios to find two of the side lengths and which quadrant you are in)
    • Given an angle measure
      • this you should be used to, graph the angle and solve
  • Complement/Supplement
    • Complement: The angle that intersects the terminal side of theta and 90 degrees (pi/2) 
    • Supplement: The angle that intersects the terminal side of theta and 180 degrees (pi)
  • Coterminals
    • Angles that share a terminal position on the coordinate plane but have different angle measures (x +_ 2pi)
  • Solve Triangles
    • Solving unknown side length (use a trig ratio)
    • Solving unknown angle (use a trig inverse)
  • Convert from degrees to radians, and radians to degreees
    • pi=180 degrees
EXTRA HELP SESSION:
There's an extra help session after school on Monday, Mr. Carofano, and I will be here to help anyone who needs it, come with questions. If you are having any trouble with the problems over the weekend you should probably clear some time after school on Monday, even if its just a half hour.

MORE EXAMPLES (Review):
Here's some examples from your book: (obviously you don't have to do all of them but pick and choose and come with questions to review) 
Pg. 333 #3,5,7,9,11,13,15,17,27,29,31,41-44,45,47,49,51,57,59,67,71,73,75,77,79,781,83,85,87,89
