Example (i): $\frac{d^3 x}{dx^3} + 3x\frac{dy}{dx} = e^y$ I Deﬁnition:The order of a differential equation is the order of the highest ordered derivative that appears in the given equation. The degree of a differential equation is the degree of the highest ordered derivative treated as a variable. I Examples: (a) @2u @x2 + @2u @y2 = 0 is of order 2 and degree 1 (b) (x2 +y2)dx 2xydy = 0 is of order 1 Linear Equations of Order One Linear equation of order one is in the form $\dfrac{dy}{dx} + P(x) \, y = Q(x).$ The general solution of equation in this form is $\displaystyle ye^{\int P\,dx} = \int Qe^{\int P\,dx}\,dx + C$ Derivation $\dfrac{dy}{dx} + Py = Q$ Use $\,e^{\int P\,dx}\,$ as integrating factor. •The general form of a linear first-order ODE is 𝒂 . 𝒅 𝒅 +𝒂 . = ( ) •In this equation, if 𝑎1 =0, it is no longer an differential equation and so 𝑎1 cannot be 0; and if 𝑎0 =0, it is a variable separated ODE and can easily be solved by integration, thus in this chapter 𝑎0 cannot be 0.

:) How engineering esque to have a MATLAB assignment for a Differential Equations ( 2 ) dk dk Men formlerna ( 1 ) kunna öfven skrifvas på della sält DE F = E'- k . dk denna differentialequation till en annan mellan x ( såsom oberoende variabel ) The most general first order differential equation can be written as, dy dt =f (y,t) (1) (1) d y d t = f ( y, t) As we will see in this chapter there is no general formula for the solution to (1) (1). What we will do instead is look at several special cases and see how to solve those. The equation from Newton's law of cooling, ˙y = k(M − y) is a first order differential equation; F(t, y, ˙y) = k(M − y) − ˙y. ˙y = t2 + 1 is a first order differential equation; F(t, y, ˙y) = ˙y − t2 − 1. All solutions to this equation are of the form t3 / 3 + t + C. Here we will look at solving a special class of Differential Equations called First Order Linear Differential Equations.
