Old Announcements:
- As discussed in class, Quiz 1 will be given on Friday, January 27, and it will be on the values of sin, cos, and tan of the angles π/6, π/4, and π/3.  You must know these 9 ratios without a calculator, and you must get all 9 correct to get full credit on the quiz.  If you not get full credit on the quiz, you will get the opportunity to retake the quiz at a later date for half credit. 
- As a reminder, Exam 1 will be given on Friday, February 10, and will cover material from Chapter 7 and Chapter 8.  You should bring a scientific calculator to use, but no graphing calculators will be permitted, and no notes or books will be permitted.
  - As discussed in class, Quiz 2 will be given on Friday, March 3 on trigonometric identities.  You will need to know the formulas for the addition and subtraction identities for sin and cos, double-angle identities for sin and cos, reduction of powers identities for sin and cos, and half-angle identities for sin and cos.  Additionally, you should still know the reciprocal, quotient, and Pythagorean identities from earlier in the course.
  - As a reminder, Exam 2 will be given on Friday, March 10, and will cover material from Chapter 9 and Sections 10.1 and 10.2.  You should bring a scientific calculator to use, but no graphing calculators will be permitted.  You will be provided the list of trig identities from class, but no other notes or books will be permitted.
  - As discussed in class, Quiz 3 will be given on Friday, March 31 on graphs of polar equations.  You will need to be able to sketch the graph of a basic polar equation (circle, cardioid, or rose), and also check polar equations for symmetry.
  - As a reminder, Exam 3 will be given on Friday, April 14, and will cover material from Sections 10.3, 10.5, and 10.8.  You should bring a scientific calculator to use, but no graphing calculators will be permitted, and no notes or books will be permitted.
