First order nonlinear ordinary differential equations

75 Views Asked by At

In my exercise I am stuck in a problem given below: $\ln\left(\frac{dy}{dx} \right) = x-y+1$ Although I could solve it if it was a linear equations. But ln() is a nightmare for me. Can anyone help me to learn this kind of problems? Thank you.

Hint: Transform it to exponential form $$\frac{dy}{dx}=e^{x-y+1}=e^x e^{-y+1}$$ and see it is separable.
