FirstOrder Linear Differential Equations from Chapter 16 / Lesson 3 19K In this lesson you'll learn how to solve a firstorder linear differential equation We first define what such an y(x)=2/(x^2C) Let's separate our variables, IE, have each side of the equation only in terms of one variable This entails dy/y^2=xdx Integrate each side intdy/y^2=intxdx 1/y=1/2x^2C Note that we would technically have constants of integration on both sides, but we moved them all over to the right and absorbed them into C Now, let's get an explicit solution I'm at the beggining of a differential equations course, and I'm stuck solving this equation $$(x^2y^2)dx2xy\ dy=0$$ I'm asked to solve it using 2 different methods I proved I can find integrating factors of type $\mu_1(x)$ and $\mu_2(y/x)$If I'm not wrong, these two integrating factors are $$\mu_1(x)=x^{2} \ \ , \ \ \mu_2(y/x)=\left(1\frac{y^2}{x^2}\right)^{2}$$

The equation is separable so you separate the variables and integrate both members of the equation (dy)/(dx) = frac (x2) x dy= frac (x2) x dx int dy= int frac (x2) x dx y = int dx 2 int (dx)/x y = x 2 ln x CSolve the Differential Equation dy/dx=xy^2 In this tutorial we shall evaluate the simple differential equation of the form d y d x = x y 2 by using the method of separating the variables The differential equation of the form is given as d y d x = x y 2 Separating the variables, the given differential equation can be written asClick here👆to get an answer to your question ️ Solve dy/dx = x^2 xy/x^2 y^2
The equation y = xc tells you nothing because c can take any value It is literally as useful as saying 0 = 0 It doesn't make any sense to manipulate dy/dx = y/x in the first place if you understand what that equation actually means, and this tutorial does not explain that to the readerExample Solve dy/dx = y(3 x);G!x"h!y" 2 Method of Separation of Variables Observe that a separable equation can be written as 1
