DifficultyChallenging +1.8 This question requires deriving a CDF through transformation of a continuous random variable, involving inverse trigonometric functions and careful consideration of the sine function's non-monotonic behavior over [-π, π]. It demands understanding of the relationship between PDFs/CDFs under transformations and handling the multi-valued inverse, which goes beyond routine application of formulas.
