To find the exact solution of the IVP , we can start by separating the variables and then integrating both sides.
Integrating both sides, we get:
(where is the constant of integration)
To solve for y, we exponentiate both sides:
Since , we can substitute these values into our equation to solve for the constant of integration :
Taking the natural logarithm of both sides:
Substituting this value back into our previous equation, we get:
Since , we know that y must be positive. Therefore, we can drop the absolute value bars and write the solution as:
Therefore, the exact solution of the IVP is .
