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

Solution

\frac{d ^{2}}{d x ^{2}} (cos (π x))

Solution

- π^{2} cos (π x)

Solution steps

\frac{d ^{2}}{d x ^{2}} (cos (π x))

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

= \frac{d}{d x} (- sin (π x) π)

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

= - π^{2} cos (π x)
