- Homework Statement
- Write the vector field F = [-4, -xcos(5x)] as a differential equation (dy/dx)

- Relevant Equations
- Dy/dx = dF/dx x dy/dF

I was thinking of using the chain rule with

dF/dx = 0i + (3xsin(3x) - cos(3x))j

and

dF/dy = 0i + 0j

but dF/dy is still a vector so how can it be inverted to get dy/dF ?

what are the other methods to calculate this?

dF/dx = 0i + (3xsin(3x) - cos(3x))j

and

dF/dy = 0i + 0j

but dF/dy is still a vector so how can it be inverted to get dy/dF ?
