1. The problem statement, all variables and given/known data Eliminate the parameter and identify the graph of the pair of parametric equations. Determine the domain (the set of x-coordinates) and the range (the set of y-coordinates). x = sin t, y = -3 sin t - 5 2. Relevant equations y = -3x - 5 Domain: (-∞,∞) Range: (-∞,∞) 3. The attempt at a solution I've already solved this equation by substitution but I don't quite understand how the domain and the range are supposed to make sense. The domain of a sine function can't be higher than one or lower than negative one, right? Because sin2x + cos2x = 1, I don't believe that it's possible. Therefore, the domain of x cannot be (-∞,∞), and the domain of y cannot be (-∞,∞). Can someone explain to me how eliminating parameters is supposed to work?
