How to solve first order nonlinear ode

WebThe most general 1st order ODEs we will study are of the form y′ = f(x,y). (1) As fcan be nonlinear in y(say f(x,y) = xy2), we are not restricted to linear ODEs. However, it should be emphasized that (1) does not cover all nonlinear 1st order ODEs. One can see this, for example, by noticing that the dependence on y′ is linear. To address ... WebFor the numerical solution of ODEs with scipy, see scipy.integrate.solve_ivp, scipy.integrate.odeint or scipy.integrate.ode. Some examples are given in the SciPy Cookbook (scroll down to the section on "Ordinary Differential Equations").
