The world we live in is full of interrelated quantities that change periodically. For example, the area of a circular body which changes as the radius changes or a projectile which changes with the velocity. These changing entities, in mathematical terms, are called as variables and the rate of change of one variable with respect to another is a derivative. And the equation which represents the relationship between these variables is called a differential equation.

Differential equations are equations that contain unknown functions and some of their derivatives. The concept of derivative of a function is one of the most powerful concepts in mathematics. The derivative of a function is usually a new function which is called as the derivative function or the rate function.

The derivative of a function represents an instantaneous rate of change in the value of a dependent variable with respect to the change in value of the independent variable. It measures how steep the graph of a function is at some given point on the graph. In simple terms, derivative is the rate at which function changes at some particular point. Both the terms differential and derivative are intimately connected to each other in terms of interrelationship.

In mathematics changing entities are called variables and the rate of change of one variable with respect to another is called as a derivative. Equations which define relationship between these variables and their derivatives are called differential equations. Differentiation is the process of finding a derivative. The derivative of a function is the rate of change of the output value with respect to its input value, whereas differential is the actual change of function.

Differentiation is a method of computing a derivative which is the rate of change of the output y of the function with respect to the change of the variable x. Derivative of the function f x is defined as the function whose value generates the slope of f x where it is defined and f x is differentiable.

It refers to the slope of the graph at a given point. Differentials are represented as d x, d y, d t, and so on, where d x represents a small change in x, d y represents a small change in y, and d t is a small change in t. When comparing changes in related quantities where y is the function of x, the differential d y can be written as:. For example, the derivative of sin x can be written as:.

In mathematics, the rate of change of one variable with respect to another variable is called a derivative and the equations which express relationship between these variables and their derivatives are called differential equations.

In a nutshell, differentia equations involve derivatives which in fact specify how a quantity changes with respect to another. The method of computing a derivative is called differentiation.
