**Question:**

Which of the four equations A)-D) has a solution that satisfies the equation \( y^2 - t^2 = 1 \)?
Transcribed Image Text:**Question:** Which of the four equations A)-D) has a solution that satisfies the equation \( y^2 - t^2 = 1 \)?
The image presents a set of four expressions labeled A, B, C, and D. Each expression defines a derivative \( y' \) in terms of the variables \( y \) and \( t \).

A) \( y' = \frac{y}{t} \)

B) \( y' = -\frac{y}{t} \)

C) \( y' = \frac{t}{y} \)

D) \( y' = -\frac{t}{y} \)

These expressions may be part of a problem set or multiple-choice question assessing understanding of derivatives and their relationships with the given variables. Each option presents a different operation and combination of \( y \) and \( t \), some incorporating a negative sign.
