  1. Question 1

    For f(θ) = a + b sin θ, the maximum value is:

    • Aa − |b|
    • Ba + |b|
    • C|a| + b
    • Da·b
    Show answer

    Answer: B

    Since sin θ ≤ 1, the maximum is M = a + |b| (when b sin θ is largest).

  2. Question 2

    For f(θ) = a + b sin θ, the minimum value is:

    • Aa + |b|
    • B|a| − b
    • C−a
    • Da − |b|
    Show answer

    Answer: D

    The minimum is m = a − |b|.

  3. Question 3

    The amplitude of f(θ) = a + b sin θ can be found using:

    • A(M − m)/2
    • B(M + m)/2
    • CM·m
    • DM/m
    Show answer

    Answer: A

    M − m = 2|b|, so the amplitude |b| = (M − m)/2.

  4. Question 4

    In f(θ) = a + b sin(cθ + d), the constant a represents:

    • Athe phase shift
    • Bthe period
    • Cthe vertical shift
    • Dthe amplitude
    Show answer

    Answer: C

    a moves the graph up or down without changing its shape or period.

  5. Question 5

    In f(θ) = a + b sin(cθ + d), the constant d produces:

    • Aa vertical shift
    • Ba phase shift (horizontal translation)
    • Ca change in amplitude
    • Da change in period
    Show answer

    Answer: B

    d shifts the wave left (if d > 0) or right (if d < 0).
