Math Analysis Ch. 5 – 6 Review
Highlight the topics below as you feel comfortable with each topic. Use your notes, practice
worksheets, and homework to study! Use your TRIG BOOK to help you with formulas. I’ve included
a few extra practice problems too. MOST problems are no calculator on the test. Keep that in mind as
you study!
Chapter 5
o 5.1 – 5.3 Trig Review
o Unit circle
o Reference angles
o Quadrants (all students take calculus)
o Finding theta given a problem like sin = ****
o 5.4 Graphing sine, cosine, tangent
o Graph at least two cycles and label all axes
o Period and amplitude
o Domain and range
o 5.5 Graphing cosecant, secant, cotangent
o Domain and range
o Asymptotes
o 5.6 Phase Shift
o y = a sin (bx – c) + d
Know how a, b, c, and d change the graph.
Chapter 6
o 6.1 – 6.2 Inverse trig
o Domain and range for inverse functions – note the restrictions
o True and false statements based on domain and range of inverse functions
o Solving inverses
o 6.3 Trig Proofs
o Pythagorean identities like cos2 + sin2 = 1
o Helpful tricks: factoring, multiplying by conjugates, common denominator
o 6.4 – 6.5 Angle Formulas – MEMORIZE!
o Sum and difference formulas for sin, cos, tan
