# Dy dx = 9x2y2

Sep 7, 2010 dt. = kx (where k is an arbitrary constant) Solution: x = Aektc. 2. dy dx dy dx. = −9x2y2 Solution: dy y2. = −9x2 dx y = 1. 3x3 + C. 5. dy dx.

∫ 1 y2 dy = − 9∫ x2 dx. using power rule. − 1 y = − 3x3 + C. Think of dy and dx each as discrete variables. So you could do something like multiply both sides by dx and end up with: iff dy=ydx And then divide both sides by y: iff dy/y=dx Now, integrate the left-hand side dy and the right-hand side dx: iff int 1/y dy=int dx iff ln |y|=x+C Remember to add the constant of integration, but we only need one. Free ordinary differential equations (ODE) calculator - solve ordinary differential equations (ODE) step-by-step In this tutorial we shall evaluate the simple differential equation of the form $$\frac{{dy}}{{dx}} = \frac{y}{x}$$, and we shall use the method of separating the variables. Original question: “What is the difference between d2y/dx2=(dydx)^2?” First, the word ‘between’ implies that you want to compare 2 things, but you provided a single ‘equation’ and nothing to compare it against.

## i.e. dy / dx = dy /du du/dx chain link chain link This result gives the first derivative of y(x).

Solve the differential equation. dy/dx = 9x 2 y 2.

### Sep 17, 2012 · (x² + 2y²)dx/dy = xy. Multiply both sides by dy to get: (x² + 2y²)dx = (xy)dy. From here, we can use a substitution where: x = yu -----> u = (x / y)

Cross Multiply. dy = 2y^2 dx Divide by 2y^2. dy/2y^2 = dx.
