Application 1 : Exponential Growth - Population Let P(t) be a quantity that increases with time t and the rate of increase is proportional to the same quantity P as follows d P / d t = k P The solution to the above first order differential equation is given by P(t) = A e k t where A is a constant not equal to 0. If P = P at t = 0, then P = A e which gives A = P The final form of the solution is given by P(t) = P e k t Assuming P is positive and since k is positive, P(t) is an increasing exponential. d P / d t = k P is also called an exponential growth model. Application 2 : Exponential Decay - Radioactive Material Let M(t) be the amount of a product that decreases with time t and the rate of decrease is proportional to the amount M as follows d M / d t = - k M Solve the above first order differential equation to obtain M(t) = A e - k t where A is non zero constant.

Ordinary differential equation From Wikipedia, the free encyclopedia   (Redirected from Ordinary differential equations Jump to: navigation search In mathematics , an ordinary differential equation (or ODE ) is a relation that contains functions of only one independent variable , and one or more of their derivatives with respect to that variable. A simple example is Newton's second law of motion, which leads to the differential equation for the motion of a particle of constant mass m . In general, the force F depends upon the position x(t) of the particle at time t , and thus the unknown function x(t) appears on both sides of the differential equation, as is indicated in the notation F x t Ordinary differential equations are distinguished from partial differential equations , which involve partial derivatives of several variables. Ordinary differential equations arise in many different contexts including geometry, mechanics, astronomy and population modelling. Many famous mathematicians have studied differential equations and contributed to the field, including Newton Leibniz , the Bernoulli family Riccati Clairaut d'Alembert and Euler Much study has been devoted to the solution of ordinary differential equations. In the case where the equation is

Page Comments Overview The equation is said to be homogeneous if P and Q are homogeneous functions of x and y of the same degree. We can test to see whether this first order equation is homogeneous by substituting . If the result is in the form f(v)i.e. all the x's are canceled then the test is satisfied and the equation is Homogeneous. Example 1: There are no terms in x on the right hand side and the equation is Homogereous. Example 2: So the original equation is not homogeneous. Methods Of Solution. A solution can be found by putting y = vx on both sides of the equation:- Example 3: Putting y - vx Since y is a function of x so is v Separating the variables Integrating Substituting (12) in equation (10) The General Form Of A Homogeneous Linear Equation.

Mathematics Differential Equations A differential equation is an equation which contains a derivative in (such as dy/dx). When given a differential equation, you will often be asked to 'solve' the differential equation or find the 'general solution'. This basically means find an expression which does not contain any derivatives. To do this you will need to integrate. Example Here is a popular one that appears in exams quite frequently, According to Newton's law of cooling, the rate at which the temperature of a body falls is proportional to the amount by which the temperature exceeds that of it's surroundings. A room is at a constant temperature of . An object has temperature when it is brought into the room and 5 minutes later it's temperature is . What will it's temperature be after a further interval of 5 minutes?
