    Simple Differential eq

    Is this correct?

    \frac{dy}{dx} = 3x^2y

    \frac{1}{y} dy = 3x^2dx

    \int\frac{1}{y}dy= \int(3x^2dx)

    \ln|x| = x^3dx + C

    Almost. Just finish up.

    y=e^{x^{3}+C}

    y=e^{x^{3}}\cdot e^{C}

    But, e^{C} is a constant we can call, say, K.

    y=Ke^{x^{3}}
