MAT 172 MIDTERM STUDY GUIDE
Quotient Identities - correct answer ✔tanθ = sinθ/cosθ
cotθ = cosθ/sinθ


Pythagorean Identity - correct answer ✔sin^2θ + cos^2θ = 1
tan^2θ + 1 = sec^2θ
cot^2θ + 1 = csc^2θ


Sum and Difference Formulas for Cos - correct answer ✔cos(a + b) =
cos(a)cos(b) - sin(a)sin(b)


cos (a - b) = cos(a)cos(b) + sin(a)sin(b)


Sum and Difference Formulas for Sin - correct answer ✔sin(a + b) =
sin(a)cos(b) + cos(a)sin(b)


sin(a - b) = sin(a)cos(b) - cos(a)sin(b)


Sum and Difference Formulas for Tan - correct answer ✔tan(a + b) = (tan(a)
+ tan(b))/(1 - tan(a)tan(b)


tan(a - b) = (tan(a) - tan(b))/(1 + tan(a)tan(b)


STUDY UNIT CIRCLE - correct answer ✔ok


tan(0) - correct answer ✔0

, tan(pi/6) - correct answer ✔√3/3


tan(pi/4) - correct answer ✔1


tan(pi/3) - correct answer ✔√3


tan(pi/2) - correct answer ✔undefined


sin(2θ) + 1 = 0 - correct answer ✔3pi/4


sec^2θ = 4 - correct answer ✔pi/3, 2pi/3


Complementary Angle Theorem - correct answer ✔sin35 = cos(90-35)


tan(pi/3) = cot(pi/2-pi/3)


sec(pi/12) = csc(pi/2-pi/12)


AAS, ASA


SSA


SAS, SSS - correct answer ✔Law of Sines


Law of Sines (ambiguous)
