Graph directional field
WebApr 20, 2024 · Hello, I need to plot a direction field for this differential equation dP/dt=0.0015*P*(1-(P/6000)) how would I do it? Thank you for helping. WebA direction field (or slope field) is a graphical representation of the solutions of a first-order differential equation achieved without solving the DE explicitly. At each point (x,y) in the plane, you plot the direction vector 1 f x , y, which is tangent to (has the same slope as) the solution curve through that point ...
