Section 1.2 (Sam)

Homework:

   Written: 4,5,7,9,12 and Appdx D: 24, 37*, 46
   Online: O1, O2, O4, O5 (these are the numbers under the current numbering),
   and Appdx D: 29, 60, 69
   The * on problem 37 means a calculator will be necessary. 

Goals

  1. Writing down a linear function given a set of information 5,12,O4,O5
  2. Recognizing what a function's graph should look like 4,7,O1
  3. Based on a graph, write down a function O2
  4. Writing down a polynomial based on information 9, O2
  5. Trig review (definitions, proofs, values of trig functions at particular points) Appdx D:24, 37, 46, 29, 60, 69 (the latter three going online) 

1. Trig to know, including problems to skim for practice. (Jessica)

  1. Given angles in degrees and radians, draw the angle, convert from radians to degrees and vice versa. (See appendix D: 1-12)
  2. Write down sin, cos, tan, sec, scs, cot of any angle 0, pi/6, pi/4, pi/3, pi/2, and all angles obtained from these angles by adding a multiple of pi/2. (appendix D:23-28)
  3. Given a right triangle with side measurements, write sin, cos, tan, sec, csc, cot of any of the angles of the triangle in terms of the side lengths. (Appendix D: 35-38)
     Similarly, given one trig ratio, find the others. (Appendix D: 29-34)
  4. Graph trig functions. (app D: 77-82)
  5. Use trig identities to simplify expressions (appendix D: 43-57 odd, 59-63), and to solve equations and inequalities involving trig functions (app D: 65-76).
         * Most important identities: sin^2(x) + cos^2(x) = 1
         * sin(-x) = -sin(x)
         * cos(-x) = cos(x)
         * sin(x+y) = sin(x)cos(y) + cos(x)sin(y)
         * cos(x+y) = cos(x)cos(y) - sin(x)sin(y) 
     Using the above, you can derive other identities:
         * 1+tan^2(x)=sec^2(x); 1+cot^2(x) = csc^2(x)
         * sin(x-y)
         * cos(x-y)
         * sin(2x)
         * cos(2x)
