For math, science, nutrition, history Find dy/dx y=1/x. Differentiate both sides of the equation. The derivative of with respect to is . Differentiate the right side of the equation. First we multiply both sides by d x dx d x to obtain. d y = f (x) d x. dy=f(x)~dx.

So we obtain: 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 as. 1 y 2 d y = x d x ⇒ y – 2 d y = x d x – – – ( i) In the separating the variables technique we must keep the terms d y and d x in the numerators with their respective functions. Equalling the red y curve and the blue x curve happens also only in (1,1) and shows that dy/dx = dx/dy = 1. Now for z=z (x,y): Equalling the blue and green functions happens in the red curve x=t, y=t, z=t^t !

Ako je funkcija f (x,y,z) neprekidna u oblasti V koja je odreñena sa: x 1 ≤x≤x 2 V: y 1 (x)≤y≤y 2 (x) onda je ∫∫∫ V f( = x,y,z)dxdydz ∫ ∫ ∫ ( ,) ( , ) ( ) ( ) 2 1 2 1 2 1 ( , ,) z xy z xy y x y x x x dx dy f xyzdz z 1 (x,y)≤z≤z 2 (x,y) Neki profesori vole drugačiji zapis: ∫∫∫ V f( = x,y,z)dxdydz 2 2 2 1 1 1

Add Δx. When x increases by Δx, then y increases by Δy : y + Δy = f(x + Δx) 2. Subtract the Two Formulas Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history Find dy/dx y=1/x.

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 Evaluate ea (a) J e oowg line integrals: .
