(d^2)/(dx^2)(cos^2(2pix))

Lösung

\frac{d ^{2}}{d x ^{2}} (cos^{2} (2 π x))

- 8 π^{2} cos (4 π x)

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (cos^{2} (2 π x))

\frac{d}{d x} (cos^{2} (2 π x)) = - 4 π cos (2 π x) sin (2 π x)

= \frac{d}{d x} (- 4 π cos (2 π x) sin (2 π x))

\frac{d}{d x} (- 4 π cos (2 π x) sin (2 π x)) = - 8 π^{2} cos (4 π x)

= - 8 π^{2} cos (4 π x)
