erweitern (vx+xsqrt(x^2-v^2))dx-x(\H(x)dx+xdv=0)

Lösung

erweitern

(vx + x x^{2} - v^{2}) d x - x (H (x) d x + x d v = 0)

vx d x + x d x x^{2} - v^{2} - x H (x) d x - x^{2} d v = 0

Schritte zur Lösung

(vx + x x^{2} - v^{2}) d x - x (H (x) d x + x d v = 0)

= (vx + x x^{2} - v^{2}) d x - x (H (x) d x + 0 = x d v)

d x (vx + x x^{2} - v^{2}) : vx d x + x d x x^{2} - v^{2}

= vx d x + x d x x^{2} - v^{2} - x (H (x) d x + x d v = 0)

- x (H (x) d x + x d v = 0) : - x H (x) d x - x^{2} d v = 0

vx d x + x d x x^{2} - v^{2} - x H (x) d x - x^{2} d v = 0
