TEST TOMORROW! (long post, just read first paragraph)

Homework tonight is to study for the Test tomorrow! If you want a quick easy way to study use that packet from Class BINGO! I have posted the answers to all the problems on the bottom of this post. For even more practice you can do some problems out of the book (again, this is a lot so just do one out of every section to make sure you know how to do everything on the Test) Below there will be a giant list of everything covered on the test, check that out make sure you know how to do it all.

Extra Practice:

• 4.1: pg. 255 #1-25 (odd) (skip 7,21), 31-51 odd, 59, 61
• 4.2: pg. 264 #5-11 odd, 23-27 odd
• 4.3: pg. 274 #5, 9-15 odd, 27,29,53,55
• 4.4: pg. 284 #3a, 5, 7, 13-16 all, 19, 21, 23, 29-35 odd, 37-43 odd, 53-65 odd

Here's a giant list of everything covered on the Test!

• 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\
