How do you solve a first order differential equation?
Steps
- Substitute y = uv, and.
- Factor the parts involving v.
- Put the v term equal to zero (this gives a differential equation in u and x which can be solved in the next step)
- Solve using separation of variables to find u.
- Substitute u back into the equation we got at step 2.
- Solve that to find v.
What is ordinary differential equation of the first order explain with example *?
General first-order equations
Differential equation | Solution method |
---|---|
First-order, homogeneous | Set y = ux, then solve by separation of variables in u and x. |
First-order, separable | Separation of variables (divide by xy). |
Exact differential, first-order where | Integrate throughout. |
How many solutions does a first order differential equation have?
Solutions, Slope Fields, and Picard’s Theorem Finally we present Picard’s Theorem, which gives conditions under which first-order differential equations have exactly one solution.
What is a first order problem?
A first order initial value problem is a system of equations of the form F(t,y,˙y)=0, y(t0)=y0. Here t0 is a fixed time and y0 is a number. A solution of an initial value problem is a solution f(t) of the differential equation that also satisfies the initial condition f(t0)=y0. Example 17.1.
What is a first order initial value problem?
Definition 17.1.4 A first order initial value problem is a system of equations of the form F(t,y,˙y)=0, y(t0)=y0. Here t0 is a fixed time and y0 is a number. A solution of an initial value problem is a solution f(t) of the differential equation that also satisfies the initial condition f(t0)=y0.
