Final answer:
The question asks to express y in terms of r, s, and x, but the provided information is incomplete. Typically in polar coordinates, y can be expressed as y = r sin(\theta). Without additional context, y cannot be precisely expressed in terms of r, s, and x.
Step-by-step explanation:
The question involves expressing the variable y in terms of r, s, and x. Unfortunately, the provided information is incomplete and lacks coherence. However, we can address a similar type of problem by assuming the relation between y and other variables in a typical polar to rectangular coordinate transformation. In polar coordinates, y = r \( \times \) sin(\theta), where r is the distance from the origin to the point, and \theta is the angle. To express y in terms of r, s (which might represent an angular displacement), and x, we would need additional contextual information describing the relationship between these variables.
