(\partial ^2)/(\partial x^2)(cos(xy))

Lösung

\frac{\partial ^{2}}{\partial x ^{2}} (cos (x y))

Lösung

- y^{2} cos (x y)

Schritte zur Lösung

\frac{\partial ^{2}}{\partial x ^{2}} (cos (x y))

\frac{\partial}{\partial x} (cos (x y)) = - sin (x y) y

= \frac{\partial}{\partial x} (- sin (x y) y)

\frac{\partial}{\partial x} (- sin (x y) y) = - y^{2} cos (x y)

= - y^{2} cos (x y)
