Unformatted text preview: ty (4) + ln( t-1) y + y = t 2 has a unique solution. Explain your reasoning. Answer: The equation is rewritten in standard form as y (4) + ln( t-1) t y + 1 t y = t Its coeﬃcients are continuous on an interval for which t > 1 and t 6 = 0. So the desired interval is I = (1 , ∞ )....
