How to solve first order separable differential equations?

Theorem The general solution of ODE to (x) d2y dx2 + b (x) dy dx + c (x) y = f (x) is y = CF + PI, where CF is the general solution of the homogeneous form to (x ) d2y dx2 + b (x) dy dx + c (x) y = 0, called the complement function, and PI is an arbitrary solution of the full ODE, called the partial integral.

How can we solve differential equations using the separable method?

Rewrite the differential equation as dyg (y) = f (x) dx. Integrate both sides of the equation. If possible, solve the resulting equation for y. If an initial condition exists, plug the appropriate x and y values ​​into the equation and find the constant. 17

How to solve a separable differential equation?

A first-order differential equation is said to be separable if, after solving the derivative dy dx = F(x, y), the right-hand side can be factored as “a formula for x only” multiplied by a formula for y only” , F (x, y) = f (x) g (y).

Is the differential equation separable or separable?

A first-order differential equation y ′ = f (x, y) is called a separable equation if the function f (x, y) can be resolved as the product of two functions of x and y: f (x, y) = p (x ) h (y), where p (x) and h (y) are continuous functions.
