Existence and Uniqueness in a Concrete Example

DIFFEQ-UYEEXV

Consider the first order differential equation:

$$\begin{equation} \frac{dy}{dt} = \frac{t}{y}, y(0) = 0 \end{equation}$$

Which of the following statements is true?

A

There exists a unique solution passing through the point $(t=0,y=0)$

B

There exists a unique solution passing through the point $(t=0,y=0)$ but it may not exist for later times.

C

There is no guarantee of a unique solution passing through $(t=0,y=0)$

D

There do not exist any solutions passing through $(t=0,y=0)$
