I need to solve for y

[tex]\int\frac{dy}{y}=k \int dt[/tex]

[tex]ln(y)=kt[/tex]

[tex]y=e^{kt} +C[/tex]

is this correct? also, I've always wondered why the integral of [itex]dy[/itex] goes away? the integration of [itex]dx[/itex] becomes x, but what about dy? Also, if I were to integrate x^2 dx... the dx goes away after that integratin as well, why is that?
