chapter we deal only with ordinary DEs‚ NOT partial DEs.] The order of a d.e. is the order of the equation’s highest order derivative; and a d.e. is linear if it can be put in the form any (n)(x)+an−1y (n−1)(x)+· · ·+a1y (1)(x)+a0y(x) = F‚ 1 where ai‚ 0 ≤ i ≤ n‚ and F are all functions of x. For example‚ y = 5y and xy − sin x = 0 are first order linear d.e.; (y )2 + (y )5 − y = ex is third order‚ nonlinear. We observe that in general‚ a d.e. has many solutions‚ e.g. y = sin x + c‚ c an arbitrary

Non-violence is more effective than violence because it helps resolve arguments in a peaceful‚ not harmful way without causing any damage. Non-violence means the use of peaceful means‚ not force‚ to bring about political or social change. People will have to wait for a change‚ but it will be a better and greater change. To begin with‚ non-violence is the most effective method for change because it’s safer. Violence is putting people’s lives in danger. Safety is “safer” for everyone. Non-violence

collection of these treasures can be seen at the National Archaeological Musuem in Athens. The Mycenaean were also literate and wrote in a script known as Linear B. This script is an early form of Greek which is unrelated from Linear A from the Minoan Civilisation of Crete. It has however been deciphered. Other examples of the script Linear B have also been found on Crete‚ which has led to the possibility that the island may have been invaded by the Mycenaean people at around 1500 BC. At around

shifts in demand for the product or service. Demand estimation serves two managerial objectives: (1) it provides the insights necessary for effective management of demand‚ and (2) it aids in forecasting sales and revenues. The theory SIMPLE LINEAR REGRESSION Relationships‚ among other things‚ may serve as a basis for estimation and prediction. Simple prediction—when we take the observed values of X to estimate or predict corresponding Y values. Regression analysis uses simple and multiple predictors
