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

Lösung

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

Lösung

- 2 y^{4} cos (x y^{2})

Schritte zur Lösung

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

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

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

\frac{\partial}{\partial x} (- 2 y^{2} sin (x y^{2})) = - 2 y^{4} cos (x y^{2})

= - 2 y^{4} cos (x y^{2})
