1.) y' + 4y = 2x*e^(-4x) Integrating factor = e^(∫4 dx) = e^(4x) Multiply both sides of the D.E by the integrating factor: y'*e^(4x) + 4*e^(4x)y = 2x d/dx[y*e^(4x)] = 2x y*e^(4x) = x² + C y = x²*e^(-4x) + C*e^(-4x) 2.) xy...

xy y' = x² + y² y' = (x/y) + (y/x) let y = xv ; y' = xv' + v xv' = 1/v ∫ v dv = ∫ 1/x dx v² = 2 ln|x| + C₁ (y/x)² = 2 ln|x| + C₁ y = ± x √(2 ln|x| + C₁) Answer: y = ± x √(2 ln|x| + C₁)

1 a. L(di/dt) + q/C = 0 i = dq/dt so di/dt = d^2 (q)/dt^2 L(d^2 (q)/dt^2 + q/C = 0 or q = - LC( d^2 q/dt^2)

Because the value of the function varies continuously with time, you cannot get an answer for this question from only "algebraic steps." This is why Newton invented Calculus. Just take the integral of the acceleration function to...
