## What are the applications of first order differential equation?

We look at two different applications of first-order linear differential equations. The first involves air resistance as it relates to objects that are rising or falling; the second involves an electrical circuit.

## How do you solve first order differential equations?

follow these steps to determine the general solution y(t) using an integrating factor:

- Calculate the integrating factor I(t). I ( t ) .
- Multiply the standard form equation by I(t). I ( t ) .
- Simplify the left-hand side to. ddt[I(t)y]. d d t [ I ( t ) y ] .
- Integrate both sides of the equation.
- Solve for y(t). y ( t ) .

**What are the physical applications of first ordered De and give two examples?**

Applications of first-order linear differential equations include determining motion of a rising or falling object with air resistance and finding current in an electrical circuit.

### Where can we apply differential equations?

Ordinary differential equations applications in real life are used to calculate the movement or flow of electricity, motion of an object to and fro like a pendulum, to explain thermodynamics concepts. Also, in medical terms, they are used to check the growth of diseases in graphical representation.

**What is a first order problem?**

First-order problem solving allows work to continue but does nothing to prevent a similar problem from occurring. Workers exhibit first-order problem solving when they do not expend any more energy on a problem after obtaining the missing input needed to complete a task.

## How many solutions does a first order differential equation have?

one solution

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 are the real life applications of differential equations?

**What are the real life applications of partial differential equations?**

Partial differential equations are used to mathematically formulate, and thus aid the solution of, physical and other problems involving functions of several variables, such as the propagation of heat or sound, fluid flow, elasticity, electrostatics, electrodynamics, etc.
