Use implicit differentiation to find dy/dx for question x^2y^2=1 asked in CALCULUS by angel12 Scholar implicitdifferntiation;. Example 1 d 2 ydx 2 − y = 2x 2 − x − 3 (For the moment trust me regarding these solutions) The homogeneous equation d 2 ydx 2 − y = 0 has a general solution y = Ae x Bex The nonhomogeneous equation d 2 ydx 2 − y = 2x 2 − x − 3 has a particular solution y = −2x 2 x − 1 So the complete solution of the differential equation is. Let's simplify it First dy/dx = (y/x 1)/(y/x 1) Taking y = vx dy/dx = v xdv/dx Therefore, dx/x = (v 1)dv / (v^2 1) Integrating we get log (1/x) logc = arctan (y/x) 1/2 log.

Example 1 Solve the differential equation dy / dx 2 x y = x Solution to Example 1 Comparing the given differential equation with the general first order differential equation, we have P(x) = 2 x and Q(x) = x Let us now find the integrating factor u(x) u(x) = e ò P(x) dx = e ò2 x dx = e x 2 We now substitute u(x)= e x 2 and Q(x) = x in the equation u(x) y = ò u(x) Q(x) dx to obtain. (2) Let y 1 (x) and y 2 (x) be any two solutions of the homogeneous equation, then any linear combination of them (ie, c 1 y 1 c 2 y 2) is also a solution (3) The general solution of the differential equation is given by the linear combination y(x) = c 1 y 1 (x) c 2 y 2 (x) where c 1 and c 2 are arbitrary constants, and y 1 (x) and y 2. Since eax → ∞ for x → ∞, a must be 0 b can be any number So c eibx is the correct eigenfunction of d/dx Relationship of Quantum Mechanical Operators to Classical Mechanical Operators In the 1dimensional Schrödinger Eq.

Answer (1 of 3) Okk Let's see I will try to simplify this expression first ( I have used Wolfram Alpha app to cheat, hehe) So, written in a better fashion, your expression is And now doing the derivative, we have, I hope this helps. Ydy F x 1 dx 1 F x 2 dx 2 =0 then set all the differentials except the ones in question equal to zero (ie set dx 2 =0)which leaves F ydy F x1 dx 1 =0 or F ydy = −F x 1 dx 1 dividing both sides by F y and dx 1 yields dy dx 1 = − F x 1 F y which is equal to ∂y ∂x 1 from the implicit function theorem 6.  Substitute y = t x t ( t 2 x) = ( t − 2 x) y ′ Note that y ′ = t ′ x t t ( t 2 x) = ( t − 2 x) ( t ′ x t) After some simplifications you get t ′ ( t − 2 x) = 4 t Consider now x ′ = d x d t x ′ x 2 t = 1 4 Which is easy to solve.
