Tomorrow's test will cover identities (sections 5.1 and 5.2) and solving trig equations (section 5.3).
- You will be given a blank unit circle
- 3 forms of the Pythagorean identities will be provided
- The best way you can study is to complete the review multiple choice questions provided in class, and review today's stamp problem!
Here's an outline of exactly what's on the test tomorrow:
- Simplify/verify trig identities
- Using Pythagorean identities
- With factoring
- "Diamond method/style" (if there's 3 terms)
- Factor out a greatest common factor (GCF)
- Difference of squares (2 terms)
- Adding/subtracting fractions
- Find a common denominator and simplify
- "Foiling"
- Remember, (a + b)^2 IS NOT equal to a^2 + b^2 (We have to "foil," so we'd get a^2 + 2ab + b^2)
- Solving trig equations
- Isolate/solve for the trig term (get it "by itself")
- Taking square roots (remember the + or -)
- Combining like terms
- Substituting using Pythagorean identities
- Factoring, "quadratic or diamond method/style" (3 terms)
- Move all terms to one side and then factor
Lastly, here are the multiple choice answers so you can use them to study!
