Mr. Max says that trig identities is basically the same as solving puzzles in class
there is never the solution only a solution
there is never the solution only a solution
Techniques to assist proving identities
1.reduce (simplify complicated side to try to "match" the simpler side)
2.work each side independently to some intermediate expression
3. DO the addition / subtraction of the rational expressions.
4.DO the multiplication / division of the same rational expressions.
5. Simplify GCF's ALWAYS (ie. factor if you can)
6. Factor, Factor, Factor
7.try multiplying both numerator / denominator by same expression to get to know identities.
8. IF possible? rewrite all trig. functions as sin(x) or cos (x);look for patterns
Todays assignment is exercise 15 questions 1-14
