### Density plot of asymptotic behaviour of a linear system

Good morning, I have an ODE linear system $\dot{\vec f} = A \vec f$ depending parametrically to two real parameters, s and p. I'd like to get a density map of the solutions of $f_A/(f_A+f_B)$ at ...

### Plotting surfaces described by redundant variables - Alternatives to use of Eliminate + ContourPlot3D

Suppose I want to plot a surface defined by equations involving redundant variables. Consider, for example, plotting the surface defined by the equations:  \left\{ \begin{array}{l} \cos x + \sin y = ...
