    Given x = 3 2 sin ⁡ ( θ ) , express tan ⁡ ( θ ) in terms of x and simplify as much as possible.
    Select one:
    a. tan ⁡ ( θ ) = x 9 4 − x 2
    b. tan ⁡ ( θ ) = x x 2 − 4 9
    c. tan ⁡ ( θ ) = x 9 4 + x 2
    d. tan ⁡ ( θ ) = x 4 9 − x 2
    e. tan ⁡ ( θ ) = x 4 9 + x 2
    f. tan ⁡ ( θ ) = x x 2 − 9 4
