## What is the application of exact differential equation in our real life?

Common practical applications in these texts include population growth/decay, mixing problems, draining tank/Torricelli’s Law problems, projectile motion, Newton’s Law of Cooling, orthogonal trajectories, melting snowball type problems, certain basic circuits, growth of an annuity, and logistic population models.

## What is application of linear differential equation?

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.

Why do we need ordinary differential equations?

Differential equations are very important in the mathematical modeling of physical systems. Many fundamental laws of physics and chemistry can be formulated as differential equations. In biology and economics, differential equations are used to model the behavior of complex systems.

### Why are differential equations important in physics?

In order to understand the behaviour of a physical system it may be necessary to set up a differential equation which relates the way in which the properties of the system depend upon one another.

### What does differential equation represent?

In mathematics, a differential equation is an equation that relates one or more functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two.

What are differential equations used for in engineering?

Differential equations are mathematical tools to model engineering systems such as hydraulic flow, heat transfer, level controller of a tank, vibration isolation, electrical circuits, etc.

Why is differential equation very important in engineering?

It is practically important for engineers to be able to model physical problems using mathematical equations, and then solve these equations so that the behavior of the systems concerned can be studied. It is very difficult to attract students to read boring formulas without variation of presentation.

#### What are the applications of differentiation and integration?

Differentiation and integration can help us solve many types of real-world problems. We use the derivative to determine the maximum and minimum values of particular functions (e.g. cost, strength, amount of material used in a building, profit, loss, etc.).
