is it ? I am not sure about what you have written
OpenStudy (anonymous):
it say so in the book
OpenStudy (anonymous):
?
OpenStudy (anonymous):
i dont understand....its says that i have to find equation, which solution is y= e^(cx)
OpenStudy (anonymous):
so, as far as I know,
y' = Ce^(Cx)
Still Need Help?

i got the same result
OpenStudy (anonymous):
so probably something is wrong with your book or something is wrong with both of us

Well you can see that
\[y(x) = e^{Cx} \]
implies that
\[y'(x) = Ce^{Cx} = Cy\]
But apparently your book would like to get rid of explicit mention of C.
\[\ln(y) = \ln(e^{Cx}) = Cx\]
so \[C = \frac{\ln(y)}{x} \]
and so plugging that in,
\[y'(x) = y\cdot \frac{\ln(y)}{x} \]
OpenStudy (anonymous):
y=e^(Cx)
y'=Ce^(Cx)

Don't seem alot of questions that make you go backwards on differential equations
