Apr 29, 2008 · How do I find the solution to the differential equation: dy/dx= xy. Please break down the work into step and specify any rules used to solve the problem. Here's the work I've done so far: dx * (dy/dx)= xy (dx) dy * (1/y) = (xydx/y) dy * (1/y)= (d/dx)x. dy * (1/y)= (1/2)x^2. ln (y)= (1/2)x^2. Thank you,

18. Find the general solution of y 2 dx + (x 2 – xy + y 2) dy = 0. Solution: Given equation, y 2 dx + (x 2 – xy + y 2) dy = 0. 19. Solve : (x + y) (dx – dy) = dx + dy. [Hint: Substitute x + y = z after separating dx and dy] Solution: Given differential equation, (x + y) (dx – dy) = dx + dy (x + y) dx – (x – y) dy = dx + dy

The derivative of with respect to is . Differentiate using the Exponential Rule which states that is where =. Mar 19, 2009 · F (x,y) = 0 then derivative dy/dx is given by formula. dy/dx = - (∂F/∂x)/ (∂F/∂y).. (@) Now let's say we have implicit function given by. equation f (x,y,z) = 0.

Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more.

Homogeneous differential equations y`=f (x y) Can be solved by replacement z x y = y`= z+xz`.

dy/dx = - (∂F/∂x)/ (∂F/∂y).. (@) Now let's say we have implicit function given by. equation f (x,y,z) = 0. We can talk about functions. z = z (x,y), x = x (y,z) and y=y (x,z) and their partial derivatives which can be calculated according to (@). So we obtain: The differential equation of the form is given as.
